Best CPU upgrade

Recommended Posts

Hi all, at the moment I have an i5 quad core 750 2.67 ghz processor and am thinking towards an upgrade. I wish to know what the next progressive step for a processor would be to run P3D 2.0 as it looks to be less CPU needy and moving towards GPU doing a lot more of the work, which brings me to my next question, would I be better saving for a new GPU instead and sticking with my current CPU?. I have a 550 gtx ti and run P3D quite smoothly, but would love to add some better weather and reduce blurries at high speed down on the deck flying.

and, would it be better to go for a higher clock duel core or a lower clock quad?

 

Finally, after looking through all the forums on the subject, there just does not seem to be a straight answer to this other than being directed to another thread that makes no sence, I have P3D on an academic licence, will it cost me to upgrade to version 2.

 

 

many thanks, Gingerterry

Your CPU isn't very good. You are gonna need a new CPU and GPU in my opinion.

 

I'd say the same even if you were using FSX.

 

Yes, version 2 is a new product and you have to pay for it. Same as FS9 to FSX.

Thanks Bonchie, what is a mid range CPU and GPU then?

 

Buy used if price is an issue and try to get the best you can. I've gotten plenty of parts off of ebay. 

 

I think you need to at least be looking for a 770 or higher for a GPU because P3D will make heavy use of it. CPU's, maybe find an ivy bridge and OC it if you can't afford a Haswell.

Its a bit of a minefield I remember from when I last built this rig about 3 years ago. Is it better to go for the highest clock speed you can get, I mean, is an i5 with a 3.4ghz clock, better than an i7 with a 3ghz clock say?

thanks,

Hey Gingerterry,

 

Go for the best Processor You can afford - Preferably Pentium - and Allways go for the fastest in its class - definatly aver 3.0 ghz !

 

When I upgraded my Box - the biggest jump in frame rate - was going from a 2.6 ghz Chip to a 3.5 ghz Chip !

 

Good Luck !

I'm sort of in the same boat myself so this is what I'm going do. Save first then wait until v2 is released, test it in my current system and then based on actual results I will make a decision.

 

We don't know what v2 is going to bring to the table, in my personal point of view everything that has been talked about in here and other forums is pure speculation. 

 

Just my 2 cents.

Fastest doesn't necessarily mean better, there is another piece of info that most people don't pay attention to, and that is the L3 Cache. When looking for a processor upgrade, I always go with a combination of the highest cache combined with clock speed that I can afford. The more cache the better performance, of course this also affects price.

Simmerhead: I think your linked information is not true for P3D 2.0:

 

I would suggest to proceed as mentioned by Carlos. Wait and see what comes along.

 

We know that 2.0 is much more GPU dependent but we con't know it needs more GB or higher computation skills. So it might be better to have a 770 with 4 GB than a 780 with only 3 GB of RAM.

We don't know what it needs as a CPU.

And we don't know how the roadmap for the GPU looks like: When does SLI come and how does it support 2.0? Maybe it is a reasonable way to start with a 670/680 now and buy a second one once SLI is active, maybe not!

 

I for myself hold myself back for the moment to wait and see what comes up to us. Things may be clearer in a couple of days. And most likely prices will drop in the meantime... ^_^

Wise advice. Last summer I could/would have bought a new system but I decided to wait for P3D. Since flightsimming is the ONLY thing I do on my PC (besides things that could also be done on a cheap laptop) I decided it wouldn't be wise to upgrade with FSX in mind, which would be rather useless anyhow. I will defenitely wait for P3D, see how it performs on my PC and then decided what to do: upgrade some parts or get a completely new PC (using information from other users).

 

P.S. I certainly would NOT read NickN's bible. Certainly not for P3D but also not for FSX. I think it's er... well, not exactly something I would advice to anyone.

The point that Nick Needham makes, and which still will hold true when P3D v2 comes along: Get the best CPU and GPU you can get! There is no cheap way to get a top notch simulator rig. FSX, P3D, and P3D v2, will swallow every MHz you can throw at it if you intend to install complex aircraft, scenery, traffic and weather addons. The only question still in the open is if a SLI setup is in order, but you can always go SLI when P3D v2 comes by adding a second, third or fourth video card.

LOL I don't need NickN's bible to figure that one out! ^_^ It might well be that he is making that point but he managed to completey burry it in a lot of text that has you doing a lot of very unnecessary and useless things, which is why I never point people to his bible... But anyway, if the point you were trying to make is 'Get the best CPU and GPU you can get!' then of course I fully agree with that! ^_^

He he. Yep, there's a lot of words in there. :)

 

But, I still think the guide holds merit. If you are cluless his guide is a good starting point for getting it all in one place. If you are to enjoy the full potential of FSX/P3D you will need to understand a few basic things about computers, Windows and the sim's engine. If people took the time there would be a lot less quesions asked and more time to fly as a result. Asking in forums will give you all kinds of answers from all kinds of people. Unless you dig into the problem yourself you will have a hard time separating good advice from bad advice, and there is plenty of the latter.

Get the best CPU and GPU you can get!

 

Getting the best cpu/gpu can be very expensive. Now if you are in a budget like some of us may be, then you would have to wait and see what v2 brings and after a few tests on you current hardware, you can then pinpoint where your bottleneck is.

 

That said and if money is no object, by all means get the best there is.

 

I think that if V2 is really optimized for performance (like LM has stated) then even with my old pc specs I should be fine.

 

Of course if I wanted to fly at max settings then I would have to take into consideration the test results and spend my money on the piece of hardware that's going to make a bigger difference.

Hence the "you can get" part. :)

 

I was fine with FSX back in 2006 on a 1400MHz computer. While everybody was whining I was out flying and having fun. The sim is highly configurable and can be made to work on very modest computers, but people doesn't just want to have cake, they want to eat it too.

 

Even if parts of the ESP rendering engine gets rewritten you will still want a CPU and GPU that match eachother. It isn't simply a case of offloading a few processes to the GPU and then not needing a stellar CPU anymore. The biggest theoretical benefit with GPU offloading is the ability to free VAS and have less risk of OOMs with heavy use of the sim. But the current sim allready does that (all graphics in FSX and P3D are rendered with the GPU). What LM might have solved in P3D v2 is the inefficient way the GPU and CPU work together.

Thanks guys, lots to think about. I will as some suggest just wait till v2 comes out and see what I need from there. thanks.

Too little is known about P3D 2.0 to make an informed decision. We know it will use the GPU more efficiently and demand more from the GPU, but we don't know just how much. Maybe a GTX 660 will still be enough, maybe we'll all have to upgrade to the Titan.

 

Same thing with the CPU - currently, FSX and P3D don't benefit much from having more than 4 cores available. What matters is clock speed and IPC. Most likely, the same will remain true with P3D 2.0, but we just don't know. Right now, your best choice for a CPU is the 4670K or 4770K, depending on your budget. If having 6 cores available is a huge benefit in P3D 2.0, you're better off looking at the Ivy Bridge-E series for socket LGA 2011.

I just brought a GTX760 and if i have to upgrade again my wife will kill me :huh:

 

But yeah playing the waiting game now to find out if i need an upgrade or not.

this is the official reply I got from Prepar3D team by email about a month ago asking them the same question.

in my case it was 8 Core at lower GHz or 6 Core at higher GHz (OC) I was interested about.

Prepar3D v2 specifications will be out later this year but it will utilize less cores but higher GHz better.
Thank you for interest and best of luck.

Have a great day,
The Prepar3D Team

I don't know if it is also valid between Dual core and Quad core. shoot them an email and ask them.they will answer you like they answered me.

Having read the latest blog from LM it would appear that we are shifting away from CPU to GPU. My i5 750 runs at about 2900hz and this plays P3D really smoothly with the megasceneryearth v2 USA which is where I predominantly fly these days.

As such, with photo scenery, there is very little autogen until I hit the major airports of which I do own a few. I do have all the GA and airport traffic turned down because the way I see it is that this is a flight sim and not an airport sim, so don't see the point of having loads of stuff going on at an airport while your not there, on the off chance of you dropping into it.

I think instead of looking at a new CPU I will save for a better GPU. I have had my GTX550 ti for a couple of years now so due to upgrade anyway, and save again for a CPU which would probably involve a new MB too. Thanks for the replies . Terry

i5 3570k and fx6300 cpu hope the improvments are engough to turnicate fsx someday as it limitations are well known. Do not mind buying planes that are p3d comparable for carendo models i own, and A2A cessna too. If MSE works with p3d im sold right there. Get something that can scale to 2014 software is what really matters to me.

Hallo...

Well here we are 6 months later and P3d V2(.2!) is out.

 

To the OP, what did you end up doing. I ask because I have an i5-750 @4.0Ghz and a gigabyte GTX 760oC. I would say my performance is merely OK. Cloud shadows are a no no.

I was getting 28-30 fps in the air in the AXE over FTX Global last night on approach to UK2000 East Midlands but it dropped quite a bit when taxi-ing to the gate.

 

I'm wondering how much an  i5-4670K would help, anyone know?

 

Jim
