Yeah, thats a pretty good swap. Id take it. The 6750 definitely has a higher resale value over the 8800GT.
I am not sure which is faster but I believe the 6750 is. Either way it uses less power and produces less heat.
I got rid of all my 8800GT's and 9800 GT's a while back after they slowly started dying. I just flipped them all on ebay after getting the RMA's back. Those cards were great while they lasted but damn, I had 2 EVGA 8800GT's die, 1 BFG 8800GT die and a BFG 9800GT die which I was able to luckly return to BestBuy after BFG was out of business. Good riddance.
