Overclock.

[[BA]Scream]

Its not a 20% increase increase in performance, more like 4-5 FPS increase

well think about it.. i was getting 27 fps in crysis on very high without AA now i overclock it and i get 32-33 fps so thats a huge difference in small fps.. <30 lag 60> no stuter or anything
i say 30 is min for any game and 60 is only needed for very fast paced games.. San Andreas is fine at around 50 Gta 4 is playble at 30
