2 Radeon 7770's or 1 GTX 660?

[Flex0]

Hi guys, I was just wondering which would be better, my friend is building a pc and he is choosing between the two choices.

Radeons = http://www.amd.com/us/products/desktop/graphics/7000/7770/Pages/radeon-7770.aspx#

NVIDIA = http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-660ti/features

The 660 gtx will be better, it's not a good idea going with two low end cards for crossfire.

In addition to the Crossfire frame latency problems that have been well-advertised over this past year, the GTX 660 is also just a higher performing option.

A pair of 7770's in Crossfire are roughly a few percent below a single 6970. A GTX 660 is about 6% faster than a 6970. So a GTX 660 is going to be about 9% faster than a pair of 7770's in Crossfire.
