I'm thinking of getting a 780. Which would be the best price/performance/quality model?
Just in case. Can you tell me the same for a 770?
They're all pretty much the same, all that changes is the frequency it's shipped at and the cooling design.
Asus, MSI, Gigabyte, EVGA
Reference design (shipped by many manufacturers), PNY, Galaxy, Gainward, and the others
The best cooler is Gigabyte which is all that matters if you overclock.
