I don't know about EVGA, but Asus and MSI are good. I'm using MSI
card, myself (OC version). If I didn't get the MSI version, I'd go for Asus
one. However, I've heard that EVGA is good, too!
As an MSI user, I can say that the card runs great, maxing out every game out there @1080p (even Crysis 2 with new high-res pack and DX11), runs cool (38C idle, 70C full load, but that will be probably much lower for you, since I live in a hot country) and the MSI Afterburner software is great - all kinds of OC, fan tuning and monitoring.
