The ASUS or EVGA 770 is the best 770 to get, unless you want to go for more than 1920x1080p then stick with the 2gb (you can always OC this card. The Asus Direct CUII and Evga's cooling solution is superior in comparison to MSI, palit etc. Not to mention the fantastic customer service.
I personally would avoid MSI, stick with your original choice, EVGA or ASUS.
