Benchmarks have shown that 2 480 GTXs perform at the same level at 3 480GTXs and sometimes the two outperform the three.

Probably a driver issue but it shows how much of a waste it is.

Anyone who buys more than one GTX480 is wasting money.

I always stick with single GPU builds because they are the best.

I am waiting for the GTX 500 series before I upgrade from my 8800gt.
Not many games even push that card.

And hopefully they fix the issues of the 400 series when they release the GTX 500 series.
