Hello , whats better VS here

The question is
Whats better :


2x XFX AMD Radeon™ HD 7770 Black edition = http://xfxforce.com/es/Products/gra...-hd-7000/amd-radeon-hd-7770/FX-777A-ZDB4.aspx

or


1x Evga 570 SC = http://www.evga.com/Products/Product.aspx?pn=012-P3-1572-AR

 

If you're asking what to buy, for that price EVGA GTX 660 Ti FTW = http://www.evga.com/Products/Product.aspx?pn=02G-P4-3667-KR

GTX 570 and HD 7770 CF are pretty much equal in terms of performance @ 1920x. At 2560x GTX 570 is a lot faster http://www.techpowerup.com/reviews/HIS/HD_7750_7770_CrossFire/22.html

In this case better go with single fast card instead of two slower. No CF hassle, less driver issues.

 

This is the wrong section to be posting that question in lol... ^^^ Post above me is all you need to know though.

 

No , I have the 3 cards but the evga is giving me high temperatures
