HD 4830 crossfire wipes out GTX 280
 

WHAT IF YOU could build a really cheap setup that wiped the floor with a GTX 280. That’s what Hexus did with two Sapphire HD 4830s. The 4830s pull ahead of the mighty GTX 280 in most multi-GPU friendly games, at very hi-res... and when you get to comparing the bang4buck it’s almost 2-to-1 against the GTX 280. (src: TheInquirer)

Wow. Pair of these would cost $200, half the price of a $400 GTX 280.

Starting to look like ATI was right all along... the future is multiple small GPUs and not single large ones.
