I currently have an Intel Pentium Processor G620 (3M Cache, 2.60 GHz) and am wondering
if that would be bottle necking my evga gtx 550 ti. It has been said that i should upgrade
to an i5 what do you think?
Depends on the game and the settings you use, but I'd say in general it would slightly. Since you have a lga 1155 board, I'm guessing an h61, getting an i5 would be a decent upgrade for you and you would notice the improved speed. Even so, if your current CPU is enough for the games you play right now then not much of a point in upgrading just yet.
