The money is not really an issue here, but the 280 GTX looks really appealing to me since I can get it for 390 on newegg and its evga. Is the 4870 X2 that much better than the 280 GTX?
it all depends on how much you want to spend 390 is a great price for insane performence its just a litle more then a 4870 and it squashes it. then the 4870x2 is much more expensive and yes will slaughter a gtx280. if you can get sli gtx260 they will be faster then the 4870x2, draw something like 8 mre watts lol, and be very very similar in price.
