From all accounts so far- all of the major manufacturers of the GTX 770 are putting out a good product.
I went with EVGA GTX 770 2GB SC, don't regret it a bit.
I usually steer clear of Palit, Sparkle, Gainward, Zotac, or any other small name card partner, so I can't comment there- but I've yet to see a bad review of EVGA, Msi, Gigabyte, or ASUS on the GTX 770. If I had to rank em it would probably be: EVGA = Gigabyte > Msi > ASUS > Rest, with Palit maybe challenging the top tier.
