l had Radeon Hd4830 is more or less equal to the Nvidia 9800 GT .. is a face-high average cost quite content with a good deal if you do not want the best but we still want to enjoy any 3D application without too many restrictions ...
But with the Hd4870 go up in price but had a high-end and the differences you notice a lot to me ... but then of course the choice depends on the use it if ...

It would also be worth to mention that the X2 cards desn't actually use more memory then the normal cards.

The 1gb versions have 512mb to each GBU, so with todays games like GTAIV i would certainly recommend the 2gb versions.

It would seam that both the 4850 x2 and 4870 x2 should be able to handle the latest games, with maxed out, or near max grapichs settings.

In case of games like GTAIV, the port simply seams to be badly optimized, the biggest bottelneck seams to be the cpu.
