I disagree with the tripleheadtogo suggestion. While it's great to do surround gaming, or if you are limited to having only one graphics card, it actually costs more than a second 8800gt. I'd rather have options for running sli or connecting 4 radically different sized monitors. I think the point of recommending the sli board was just that it would have a second pciex16 slot on it, not to necessarily run it in SLI. Alot fo this depends on the mobo in the system. An intel mobo with 2 x16 slots does crossfire, but I believe it can also run two nvidia cards in this scenario for 4 monitor support. Also if you are gonna go with 4gb of ram then you should consider 64bit vista. Also maxed out ram on most of these systems would be 8gb which you can get for as little as 150 bucks now.
