Thread Starter 
Before I start, full specs;

E8400 @ 4Ghz
P5Q Pro + SLI Hack
2x2GB DDR2-1000
EVGA GTX 460 + MSI Cyclone GTX 460 SLI, both 1GB and stock.
Corsair VX550W
1080P res

Games with poor FPS

Bad Company 2 - maxed with 4xAA and 4xAF - 30-40FPS
Crysis Warhead - Enthusiast settings no AA - 20-40 fps at the beginning level
Metro 2033 - Very high X10 - 60s but lots of major drops here and there.


Do you think my E8400 is bottlnecking my GTX 460 SLI?

it is possible, but at 4ghz I doubt it. Those games are pretty demanding already and they might just not like SLI.

Check your GPU usage when playing those games, then you can know for sure.

strange issue, I doubt its the CPU there might be a small bottleneck but thats it. I could blame the frame drops on a slow HDD if that's your case but your overall performance looks rather sluggish. perhaps your running an unstable overvlock!

Bad company loves quads. I went from e5200 4ghz to q8400 3.2ghz and i see huge improvement. Now i can keep settings high as possible enjoying fps over 60

I'm 99% sure that there is a bottleneck when looking at this: http://www.tomshardware.com/reviews/...80,2694-6.html

It might be your motherboard running the sli on 4x/4x and not something higher.

x8/x8 doesn't have any significant loss compared to x16/x16. What's your bclk at? How are you achieving that clock speed? You may need to drop it back a bit.

Do you think my E8400 is bottlnecking my GTX 460 SLI?
As mentioned, watch GPU usage while playing. The Afterburner On-screen display functionality is really good for this purpose.

Not getting usage consistently in the 90+ range is a reasonably good sign of a cpu BN (not 100% sure-sign, as other things CAN cause this, but it's a decent indicator). Note: v-sync has to be off, and you should always run full-screen because SLI in windowed mode is unreliable.

BC2 - could easily be BN'd as mentioned it's coded for 4 cores
WH - that CPU could limit you a bit for sure, but drops to 20fps due to cpu bn would be unexpected/extreme in my past experience. That CPU should be good enough to keep you over 30fps pretty much at all times.
Metro - cpu could also possibly limit you a bit in that one if you're running at settings easy enough to put your average around 60fps. Although big fps drops are *very* common in that game no matter what rig you have.

So they are running a little slower on x8. like 1-2 maybe even less fps on x8, not a big problem.
Metro 2033 is a Nvidia game basically thats why you see good fps then the others.
Have you tried turning off background programs and unneeded process's hogging your CPU's power.
