Hi,

I am kinda new to this forum so I apologize if I am putting this post the wrong place.

I am about to build my own pc soon but the only thing that I haven't decided on ye is my CPU. I am building this computer for gaming and specially flight simulator X.

I want to be able to run my FSX very smooth with great FPS and I have tons of addons to install on it. I am also willing to overclock my cpu and have a great graphics card (amd radeon 6950 2GB).

So I was wondering if anyone can help me decide which CPU is better for fsx. i7 3770k that is ivy bridge, or 2700k that is sandy bridge?

 

Any help wold be appreciated

 

best regards to everyone!

My latest build has the new ivy bridge chip set but an i5 2700k sandy bridge processor. The ivy bridge mantra to add lots of graphics improvements for notebooks, that do not use add on graphics boards, kind of turned me off. Right or wrong, any way, the i5 is overclocked at 4.4. My graphics processor a 6990 with 4 gb video RAM. FSX and win7 x64 is installed on two separate SSD drives.

 

My Concluion: i7 with ivy might be better and of couse the letter k tells us the chips batch quality. Many believe that processing lots of data is the most important factor for good FSX Perfomance but lots of monitors, high video settings, complex aircraft and scenery will bring any system to its knees. I also think that processor selection may not be the defining solution. What is your weakest link, will overclock of processor and/or video card cause a specific combination of software to run stable? Will your lust for processor speed cause random USB, sound configuration, video processing, CDT glitches?

I'd get the 3770K.

 

Replace the thermal paste under the IHS (relatively easy), OC it to 4.6-4.8GHZ, slap in some inexpensive DDR3 2400MHZ RAM, and you will be able to play FSX like total butter.

Thank you everyone for all your replies. I think I finally decided to get the 3770K and also a liquid cooler for it as one of my friends suggested.

Do you think ram is very important, cause I have already purchased my ram. It's kingstone hyper x blue 16GB 1600c. do you think this will work?

It's kingstone hyper x blue 16GB 1600c

 

It will work, but, it is considerably slower than the 2400MHZ RAM. If you swap the RAM out for 2400MHZ, you will see a 10% increase in FPS.

That is a pretty bold claim. 10% is a very significant increase. I hope you have the numbers to back it up, as I am currently trying to decide if going for 2400Mhz RAM instead of 1600Mhz with tight timings.

 

Your claim very much contradicts the conclusions in this test: http://hexus.net/tech/reviews/ram/38613-gskill-tridentx-ddr3-2400-ivy-bridge-memory/?page=7. That's why I'd really like to see your testing results and comparisons as soon as possible before I make my choice.

 

It's especially important to me because from what I've found listed the terms inexpensive and DDR3 2400Ghz are oxymorons, at least here in Norway. However you might have access to cheaper HW or a bigger budget than I do.

 

I guess I could order it from the US, but I like to be able to do RMA as quickly and without hassle as I can in case of trouble. Sending it back and forth across the Atlantic doesn't sound like a viable option unless the RAM is very much cheaper. Please send me a link and I'll consider it.

 

All being said, even a less than 10% increase could still be worth it, as it might remove some stutter and as we all know. Even a few frames gained can sometimes make the difference between watching a rapid slideshow and flying a plane. I am eager to see your numbers asap as I want to finish my build soon.

 

Kind regards

From what I have understood memory above 1600mhz will mot give any significant gain of performance.

In benchmark tests you will see a minimal gain of performance.

Also the cas latency timings are very important.

1600 mhz at cas 6 is faster than 2000 mhz at. 11.

 

However, the price of memory is that low that I would advice the fastest memory for you budget.

Dont Agree

Think that my FSMark11 runs with 2700k and 3770k talk for itself.

the diff with 2133 cas 9 to 2250 cas8 was significant with 2700k

did some runs with 1600 cas 7 to see diff with 2133 cas 11 and the result was that 2133 cas 11 was faster dont do any tests

with cas 6 but my feeling is it can be close but not faster.

the 3770 needs fast mems atleast 2400mhz a run mine at 2800mhz cas10 , a 3770k with 1600 cas 6 to 2800 cas10 is the diff huge in fsmark11

My recomendation for 3770k not slower mems than 2400mhz , 2133 cas 9 is a little to slow for the 3770k

Ivy Bridge Memory : 1600 or better ? http://hardforum.com...d.php?t=1692486

 

Conclusion : It definitely makes sense to buy a DDR3-1600 kit, and even DDR3-1866 nudges performance forward a little. Stepping up to DDR3-2133 really doesn’t do anything though.

 

 

Sandy Bridge Memory scaling : Choosing the best DDR3 http://www.anandtech...the-best-ddr3/7

 

Conclusion : The extra bandwidth gained with the overclocked CPU doesn't exactly translate into much. The first pass of the x264 test reveals a 7% advantage for DDR3-2133 over DDR3-1333 on our overclocked CPU while the stock CPU shows a 5% increase.

The increase for DDR3-1600 over DDR3-1333 is 3% for both our overclocked and stock CPUs.

Once we move on to the second pass, there's no discernible advantage for faster memory on our overclocked system.

The Cinebench test results are every bit as unimpressive with overclocking as at stock: overclocked or not, faster memory makes no real difference (though the faster CPU clock speed definitely helps a lot).

You will have to delid the cpu for some decent overclock. Even with a watercooler.

 

Slow memory makes no sense over slow one, just make sure it's not too expensive, you don't need top of the top. Some 2133 or about will suffice.

I also agree that 10% is a bols claim, would like to see some hands on results IN FSX. Not other apps.

Its up to each one to make ther concloutions, want to see a 1600 kit outpeform 2800 cas 10 in FSMark11 :smile:

 

This do diff in FSMark11

10% is a small increase? Since when is 10% so large that people start to throw their arms into the air demanding results?!

 

10% is 20-22 FPS....

10% is 20-22 FPS....

 

I want to see that 220 FPS machine

It would also mean 100-110FPS... which is bold, yes.
