The 570 and 660 will be slower than the 295gtx?! kinda hard to believe...
How the comparison goes in terms of temps and power demand?
316W Gtx 295
268W Gtx 570
Actually a Gtx 570 is a bit better than 295.
Thats why i said not worth getting it now. U have to save up.
So just resit the heatsink ,reaply thermal paste and add some fans blowing cool air to the card.
Gtx 295 is a dual GPU and very very good.Just direct x is the problem
