4800 are getting more expensive than we though uh?
you wont see significant boost with another 512mb memory. and it's still DDR3
Oh, you mean a lot like the DDR3 that's in your supposedly stat of the art 280? So why the extra 512 there then?
Also, if you looked at any of the pricing, the 4800's are super cheap, as low as 150 for the 4850 and 250 for the 4870...
