stick w/ the 6800gt even if you don't upgrade til a long time, or the cost of 2 6600gts is the same. here's the reason... the 2 6600gts have a marginal if any performance difference over the 6800gt. as many ppl will say "oh, you can get another 6800gt down the road".. yes thats true, but more so, some apps don't even BENEFIT from SLI.... making a bad use of that second 6600gt... so the perferct plan is, buy 2 6600gt, put one in, and give the other to me =]
