Right now I have one 8800gtx, and it has served me just fine in the few months that i have had it (with the exception of Crysis and Supreme Commander). And as a part of my upgrades before starting college, probably the last hurah before i get swamped in debt


, I think I want to buy another 8800gtx for SLI. A friend of mine has an alienware with SLI 8800gtxs (e6850 processor, 2 gigs ddr2 800) and nothing gets choppy or unplayable. Know that I am not doing this so that I can play crysis maxed out, but I think that two 8800gtxs will provide better long term performance than one new card.
At least, the price is right...when the flagship gt200 cards come out I expect that they will be priced in the 500$ to 600$ price range right? Now, even
if they provide the same performance as SLI 8800gtxs, I'm still spending five or six hundred dollars when i could get the same performance from spending 300$ on another 8800gtx. Also, I figure that by the time two 8800gtxs can't handle new games coming out (1 or 2 years? is that optimistic?

), the price of the flagship gt200 cars should have dropped enough so that I can buy two of those.
Does this upgrade path make sense? Going SLI with older cards to match the performance of newer, more expensive cards, then upgrading after the older cards can't keep up. By that time, I've gotten ahead of the price curb so that the then
new hardware is already beginning to move over for even newer, more expensive parts....
any comments, or suggestions?
