Hey guys. I have a bfg 8800gt and wanting to upgrade. I was looking at the 9800gtx but I think its a waste of money compared to what I have. I was thinking of a 4850 but not sure if its worth it either.....Any suggestions as I don't want to break the bank
9800gtx = 4850. They perform the same, and both are around 10-15% faster than 8800gt. Neither are real upgrades. You'd need at least a 4870/gtx260 to get a noticable difference.
Since you use a sli motherboard, consider getting another 8800gt on the cheap. It will far outperform a single 4870/gtx260, and in most cases, outperform gtx280.
