is my CPU botlenecking my 8800gt's in sli

[rembrandt]

Im using a e6600@3gb with a asrock 650i sli MoBo, the sli slots are only 8x instead of the single slot having 16x both are PCEI 2 but in WaW I seem to be getting less FPS then I did with the single card

any help would be great

Thanks Dave

Getting less FPS than a single card would indicate a problem with the SLI profile for that game/program or the game not liking SLI.

3gig isn't going to hold back an 8800GT SLI much if at all in gaming, tho might a bit in benchmarks. Same for the x8 ports, they don't really hold the 8800GT SLI setup back much if at all except at very high res/settings which the 8800GT SLI setup isn't really suited to anyhow due to the lack of VRAM.

very new to SLI do I have to set up a profile for each game then ?? I just activated SLI in the control panel and left everything as default

The nVidia drivers have profiles for each game in the drivers which should be automatically enabled - aside from enabling it you usually shouldn't have to do anything. But its possible the drivers you have, have a corrupt or incorrect profile for a game.

Or your forcing SLI mode on in a certain mode i.e. AFR instead of letting the drivers choose.
