The problem is, NONE of the ati vendors will warranty your card if you change the cooler or overclock it. I really wish there was a vendor that would step up and give the type of support Evga has. That being said, if x58s support SLI i'm going back to nvidia cards just for the peace of mind of having evga customer service.
*knock on wood* hopefully my 4870s dont die on me prematurely.
XFX also lets you modify the card with their double lifetime warranty. If either of those companies ever sold ATI cards, they probably would win over all the customers due to the warranty.
