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.
I'll try this out and report back.

EDIT: Alright guys. I basically played the first few minutes of Warhead while Afterburner was open on my second display. GPU usage was basically identical on both gpus, fluctuating between 40-50 at the start then hitting 70-80 once you jump over that broken bridge. At this point I noticed massive artifacting. it was like the shadows of every object was out of sync and were popping out. Do you guys think the PSU might be the problem? maybe its not giving enough power to the cards.

I'm gunna test out the EVGA card alone without the SLI hack enabled. I purchased it used for $70, maybe the dude knew the problems and thats why it was so cheap. but i doubt it since the guy was very helpful and even gave me the EVGA account that was used to register the card.

Also Metro and Cryengine games are VRAM hogs, so have AB put your GPU usage onscreen as well and keep an eye on that. Lowered gpu usage can also potentially be caused by running low on VRAM, just for future reference to everyone

Games with poor FPS

Bad Company 2 - maxed with 4xAA and 4xAF - 30-40FPS
We have similar machines, but my monitor is a little smaller and I don't run SLI. When I play BC2 with EVGA Precision running, I see about 30fps(low), to 100fps(high) and about 50% to 70% GPU usage. My CPU will be anywhere from 65% to 100% operational load. I've not really looked at what particular areas of BC2 drop frame rates and gobble up machine resources, but it does happen. Vietnam seems to be a much better performer, for me at least, never see frames below 60fps.

I've gone into start/programs/administrative/services and have disabled many services from starting up at boot, other services have been completely disabled because I have no use for them. You can find out "safe" 'services' to disable or set to manual from this site. Please read over the site and the links to the services before making changes. This way you can get to know how some services depend on each other in order to work properly, or even work at all!

This will help cut back on some of the used resources of programs/services that are waiting to be used, that you may never use. Example; 'Internet Explore'. That must be disabled through 'Turn Windows Features On Off' in 'Programs and Features' under Control Panel. Disabling some services and Features should squeeze a little extra performance into your games.

Hope this helps,
Mark-
