MSI vs EVGA GTX 760 Difference

Solution
The 4gb won't matter unless you're high res gaming like 1440p or multi monitor. If you're running 1080p or less the 770 will give you much better performance.
Both are great cards. Personally, when I go with a nvidia card I always go EVGA. Their new ACX cooler is extremely high quality. I know the twin frozr is a well known and good cooler also. Really it's a win either way, but if you're going to drop 310 on a 760, why not put in another 20 and get a 770?
