So I have purchased a GTX 460 1gb to replace my old 8800 gts. Mainly because COD Black Ops played like garbage even on the lowest settings. When I bought this card I thought that all my problems would be solved but no, I can now just play the game on its highest settings but with still mediocre to unplayable fps. Is the rest of my system bottle-necking my GPU? says my cpu is at 100% while playing black ops.

Since you have an SLI board you could put your 8800GTS back in there as a dedicated Phys X card. If your previous card was a 512MB, then a 460 isn't that big of a jump as well. Anyway, that game is demanding on the CPU. Here, you can see how a 5970 scales on it with an i7 at different clock speeds
I had the same problems, poor frame rates. I swapped out the dual core and put in a Quad core setup, it now works on the highest settings no issues at all. I do not think is was ever a video card issue for this game, it is a multi-threaded game will real problems eating processor power. To old setup played COD MW2 at highest settings with my single stock Dual Core Xeon 5130 2.0 Ghz, no problem.
I spoke to soon, the game crashed my system. Had to reset the CMOS. COD Black Ops PC is the worst game I have 'NEVER' played. I have spent more time and money to try and get this working. I have come to the conclusion that the game is the problem, not my system.
