I come here posing a question about ram (of course). Does the speed of ram (i.e. 1333mhz, 1600mhz) affect gameplay at all? Right now my ram is 667mhz, and though when I got the pc, it stated it was DDR3, I believe the speed put's at DDR2. If I were to upgrade to faster ram, would that increase frame rates or just load times?
