Agreed. $217 AR X1800XT and then $239 AR 7900GT are the best choices under $300. Good to see the Sappire rebate come back as well as 7900GT prices drop. But new X1900XT for $370 and OB for $320 is starting to look good.
To the OP, the stability issues with the 7900GT's is a real issue worth considering. Just in case, I'd go with an EVGA who has shown to not only admit there is a problem but to also act quickly to resolve the problem. The 7800's didn't have that issue, but they are not good buys at current pricing. of course it all depends where you are from and your pricing. If 7800GT's saved you 20% over 7900GT's, then that would be fine. But I'd suspect that pricing is doubtful. if anything, the 7900GT is the lower priced of the two now.
