I'd get the 4870 Personally,but that's just me.Your coolling will be fine on that system unless you plan to overclock.

And yeah,When you want to improve game performance,the most integral part,is the graphics card.

Nothing runs Crisis perfectly, lol.

so then how could they have developed it?
if there isnt anything that can run it
then how could they prototype it?
how could they have debuged it?
