I saw ZOTACs overclocked card, don't feel its worth 550$ really.
I like Gigabyte and 3 years is quite a warranty.
Didn't look into EVGA yet.
Thanks for the info, do you think I should OC my CPU past 3.8GHz on stock cooling?
You'd get a slight performance increase, but I don't see it being a huge difference from what you have now.
