Is it worth upgrading from i7-4790k

Recommended Posts

Hi,

I have nearly 4 year old I7-4790k overclocked to 4.6ghz with Corsair H80 water cooler. I am finally moving from FSX to P3D and am interested in getting the best system for performance.

Is it worth upgrading the GPU from GTX 770 to GTX 1070 and ram from 8GB to 16GB to 32GB or upgrading the processor and motherboard?


Thanks

I’m using overclocked i4770K to 4,5ghz with Corsair H100. I’ve recently upgraded from Nv780 to Nv1080Ti and I’m very happy with performance of P3Dv4 and DCS World 2.5.

That 4790k is still one helluva processor, especially a bit overclocked like you have. Latest benchmarks still show it in the top echelon.

Upgrading your graphics card will make a noticeable difference. I upgraded from a 770 2Gb to 1080, and especially on P3D V4 I had a substantial improvement.

I would also suggest going for minimum 16Gb Ram. I upgraded from 16 to 32Gb ram, but did not perceive any difference, 16Gb should do it.

And, always keep your drivers updated to the latest, especially chipset, graphics and sound. I found outdated sound drivers can lead to stuttering, especially on the later versions of Windows 10. Intel also launched chipset drivers to be more compatible with Win 10 16299 and later, download and install their chipset version 10.1.1.44 and later. (The latest version is 10.1.1.45, but I could only find it on Asus's website, see driver downloads for their Z370 motherboards).

Thanks everyone for the input.

 

1. Is 1080 GTX the go to card? It seems very expensive at $600+

2. Should I upgrade for 8GB to 16GB or 32GB?

3. I am on Win-7 64 bit, is there a benefit of upgrading to Win10? I like the old interface

1- yes

2- 16

3- Win10/64 ....  I'm totally happy with Win10. There is a learning curve to finding your way around in it.

*** Your cpu is still very good.

Depending what your taste in scenery and performance. In recent days VRAM has become important when it comes to scenery detail. More you have the higher your setting you can use without compromise your performance. Many have purchase cards with 6 or more GB of VRAM due to the demands on the scenery detail and the sim itself. P3D requires 2 GB of VRAM but recommends 8 GB.

You will need to decide what is your priority when it comes how you are going to use your sim. If your the type who likes to try to max out your setting and expect to maintain good performance in high detail airports, highly detailed scenery or other graphically demanding addons, than you going need to have the enough VRAM you support it.

 

2. Should I upgrade for 8GB to 16GB or 32GB?

It depends on what version of Windows your using.

Windows home premium max is 16gb max.

Windows professional is 192gb max

Coming from FSX to P3D  I would start off with 16 to be safe and 32 for immediate future proof. 

 

3. I am on Win-7 64 bit, is there a benefit of upgrading to Win10? I like the old interface

For P3D no.   if your using Home premium or professional.

P3D uses DirectX 11 and Windows 10 supports DirectX 12.

I would only change the OS if there is a something specific I need with DirectX  12 support. Otherwise I would save myself the headache and the expense of upgrading the OS until I am ready to build new rig.

I think you could upgrade just the GPU and find you have a decent performing system with P3Dv4. 

P3Dv4 moves a significant amount of workload from the CPU to the GPU, and with any of the better aircraft and airport add-ons you do really need 4GB of VRAM as a rock-bottom minimum and really 6GB or more to maintain a comfortable amount of headroom.  A 1080 or a more powerful 1080Ti is expensive, but a pretty much necessary step up over a 770 when moving to the 64-bit P3D environment. 

The 4790K Devil's Canyon CPU is still very capable when stacked up against the current front-line consumer CPUs (e.g. i7-8700K), probably within 10-15%, and not screaming for an upgrade.

If I were building new, I would go with at least 16GB of RAM, but honestly, I'd try it out with your current 8GB config first, because it's likely you don't really need more, and if you do, you'll want to replace (not add to) the 8GB you have with a larger set, as mixing and matching RAM is a generally bad idea, and it's not likely you can find a good match for your current older DIMMs now.

I absolutely would NOT switch to Win 10 until you have to (e.g. because you build a new PC with a motherboard that's sporting a chipset not supported by Win 7).  There is no advantage to running Win 10 over Win 7 when running P3D, and plenty of butt pain associated with Win 10's nannybot automatic unwanted OS and driver updates, learning the new interface, etc.

Lately, I've been thinking about upgrading from my 4790K (just finished my third 8700K build on spec... that is a great CPU) but I'll be staying with it for another year or so.  The 4790K/1080/16GB combo still runs P3Dv4 very well.  If you want to get more out of your current system you should definitely consider a new GPU (I went from a 970 to the 1080 after moving from FSX to P3D, and the 1080 brought so much more out of P3D) and fast memory (at least 2400 and then overclock it).

HTH and good luck,

Greg

What about the 1080TI?  Would that be any better?

I would surmise, yes. 

That said, because the prices have gone crazy due to the 1080Ti's popularity for use in virtual currency mining, I'm not sure if the cost-benefit tradeoff on the Ti is there while prices remain bid up so high.

Indeed, $500-600 difference in price between the two, not sure if it would be worth the cost.  I have been thinking of updating my 980TI but at the current price I think I'll hold off.  Thanks for your reply Bob.

I went from a 770 to a 1070 when I moved to P3DV4 and am very happy with the performance.

Go to 1070 and 16 gig of ram, 32 if you think your going to run utlive (it uses almost 900 on mine) that's what I have and works for me.

I am also curious about this. Would be very interested in hearing the actual experience of someone going from 4790k system to 7700 or 7800K.

I upgraded from 1 year ago my gpu from a 980 to 1070, and that made a considerable difference in performance, and also important, enabled me to run at high AA settings. 

I am curious what kind of gains I would experience going from 4790K, GTX 1070, DDR3 and to a 7800K overclocked at 4,8 GHZ, GTX 1080TI and DDR4.

1. Graphics cards have gotten very expensive due to the high demand. What's important is the resolution your looking for.

  • AT 1080P, GTX1060 6GB should work fine with fairly high settings, A GTX1070 for max settings   
  • AT 2k-4k or VR, GTX1070 should work fine with fairly high settings, A GTX1080 series for max settings 

2. Memory is still relatively cheap, get as much as you can fit on your motherboard. 

3. As long as you can get updated drivers for all your hardware Windows 7 is still ok. 

I'm happy with my processor, but since you can't find any Z97 boards around anymore, I'm not sure what to do if mine goes.

And thanks for reminding me I'm due for an GPU upgrade myself.

My 4790k at 4.6 runs noticeably slower than my 6700k at 4.4 in P3D4. I'd say 13-23fps on the 4790k in one scenario compared to 19-27fps for the 6700k. The 6700k was never a very good overclocker and I struggle to even get it to run at 4.4. Voltage and temps are also not the problem. The board just refuses to be stable past 4.4.  Bad motherboard or just luck of the silicon I don't know. I too am on the cusp of upgrading the 4790k to an 8700k for the same reason and am hoping to get 5.0 out of it. I assume that the 8700k will also be noticeably faster than the 6700k. I am hoping to see my minimum fps increase to a lot closer to 30 in the same scenario which would be ideal. It's a lot of work, time and money to spend for what could be minimal gains and I am still deciding if it is worth it.

Your Video card is what you should upgrade to no less than a 1070 a 1080Ti is best.  16G memory minimum. The gains of upgrading the processor and mother board wont be as great as upgrading your video card at this time. So I would get the video card now and wait a year or so on the rest. The 4790 is still one of the best chips out there.  Josh

 Its 15% to the 4790k and it Clock not as the 8600k ,30% is easy double gain. The 4790k is old and not one off the best nowdays 

1080ti with a 4790k att 4.6-4.7ghz you get cpu bound a 1070 or 1080 do the same work probaly even the 1060 6gb, you need +5ghz with a coffelake to match the 1080TI

The link was to the 8600k review just because it had all three CPUs (4790k, 6700k and 8700k) in the IPC results. Note that the results in the linked table are all at the same clock speed to show comparative single thread measurements. I agree that the difference between the 4790k and 8700k is about 15% but j0nz was talking about the 6700k and the 8700k which is a much smaller difference for the same clock speed.

Remember we are talking about flight simulators here, not synthetic benchmarks..  :cool:

I would support staying with the 4790 and getting a better video card (budget permitting)..
