Oops I forgot to add..
I'm not really a hardcore gamer.. but i do like nice visuals.. I know that due to my PC.. I have been restricted to better options.. but I would like to start off with this PC so that I can keep it for other uses.
The games I would like to play would be..
GTA IV on medium-high setting..
Crysis 2 on medium-high settings
Dirt 3 on high settings.
I will mostly be playing in 1280 x 720 - 1600 x 1000 resolution.
Thanks once again.
