Currently I am running and I7 920 6GB of TRI channel ram and 2 80GB WD blue HDD in Raid 0 on a EVGA E760 3way Classified board with 3-260GTX in SLI and a 9600 for Physx. The rest of the rig is in my SIG. I notice when I'm gaming on WOW (don't start bashing on it) in 25 man Raids my FPS take a serious hit down in to the 20-30 FPS range, and the game starts lagging. My ping is fine down in the 40-50 MS range so that's not the issue. So I am trying to figure out what will benefit me more a SSD or upgrade ram from 6GB to 18GB or 24GB or buy a new video card and drop the SLI? P.S. Computer during gaming is using over 3GB of ram. Comments/Suggestions please.
