[color=#99cc00]my opinion is that nvidia are a lot expensive simply becoz of the label but they also have a lot of support and can run some games smoother even tho that ati has up ther standerds ALORRRT im really sure what i would go for [/color]
The GTX285 is not even in the same class as the 4980..
Here go classes; 4850 = 9800gtx, 9800gtx+, GTS250 4870 = GTX260 4890 = GTX260 c216 & GTX275 GTX285 = no really ati competitor here. GTX295 = Well.. The 4870x2 is SUPPOSED to be a competition... but not even close.
Well anyways, the GTX285 is best out of those two.
Basically, what Green said. ATi's drivers suck, the cards may look good on paper but the fact is they aren't, maybe if the drivers worked Nvidia would have some competition, hell I would get an 8800GT over a 4870 any day...
i think you cant compare the gtx 285 to the 4890 like green said and yes nvidia has better drivers but expensive as hell cards and power consuming ones. this thread may become a fanboy fight
