GTX 480 Bottleneck?

post #1 of 27
Thread Starter 
Hi i just recently bought a evga gtx 480 and was wondering if my current cpu(sig rig) is going to bottleneck the gtx 480? i usually use the rig to game on like bfbc2,crysis2,CoD blk ops, and want it to run BF3. oh and i game at 1080p

thanks in advance.

Not really. In a few titles you might see lower performance than expected, but the only things that come to mind are Starcraft II and F1 2010.

If i overclock the q9400 3.8-4.0ghz solve the problem?

In BF BC2 you'll be bottlenecked by the CPU for sure. There are some other titles where you'll be bottlenecked though. I had a Q9550 @ 3,9GHz and it bottlenecked my OC'ed GTX 470 a bit, especially in Vantage.

i dont think a single GPU will be enough to bottleneck your CPU in a noticeable manner

It would help, but not eliminate it. The truth is that you might "bottleneck" in a lot of games, you're still going to max it. It might be the difference in getting 70 FPS vs getting 90 FPS. Don't worry about it. All your games should play pretty well.

BC2 is multithreaded, so while there may be a slight bottleneck present, FPS should still be very good.

it will bottleneck, but only programs that use 2 cores or less, and you probably wont notice anyway
post #8 of 27
doubt it, I don't bottleneck using a 570 and a Q8300 at 3.1. you have a higher clocked CPU so you should eliminate any possible bottlenecks.

No,you're fine..

I have tested possible bottleneck scenarios and I have found out that a Q9550 @ 3.5GHz does not bottleneck a OC'd GTX480 @ 850/1025MHz (bit faster than stock GTX580)..

In for example Crysis 2 Bench DX11,Ultra @ 1280 x 1024 (which makes a CPU intensive test) a Q9550 @ 3.5GHz scores the same as Q9550 @ 4GHz and GPU usage is 99%..

At higher resolutions such as Full HD for example there would not be any CPU bottleneck for sure as all strain would be on GPU..


Here's a Q9550 @ 3.9GHz maxing out a GTX480 @ 850/1025MHz at 1280 x 1024 res..
