Are these enough?

[Zangetsu21]

I run my 3570k at stock clocks and I run Shadow of the Colossus 60fps @1080p internal res so you won't have a problem with that at least.

I also play God of War 1 and 2, Final Fantasy X, X-2 and XII at full speed with audio and all, also @1080p.

These i5's can really perform ^^

+8gb ram win 7 64 bit for pc gaming and pcsx2 emulator

run stock clock recommended!
running Overclock cpu shorter cpu life

just compare amd graphic card 7790 2gb ddr5 oc and nvidia graphic card gtx 650 ti 2gb ddr5 before buy

4Gb ram is enough for pc gaming & Pcsx2 emulator not use ram too much.it uses only 128-256 mb ram i think.
if u want to spend money on ram,then go ahead.8gb is maximum.no use of going up from 8gb !

My laptop have 2Gb ram pre-installed & i'm not going to upgrade it till any modern pc game needs that much ram.
but i can multitask,play pc games,play on pcsx2 emulator on my 2gb ram.
