I really just buy whatevers cheapest for the model I want, or has the best package deal at the time on newegg. Ive never had a horror story with any brand. Ive owned XFX, eVGA, MSI, Zotac, Gainward, Asus, ATI, Sapphire, and Powercolour before. No issues with any of em.

I only worry about brand with mobos, memory, and PSUs.
