I won't be overclocking and most of the games I'm planning to play aren't really heavy like BF3 and Crysis.
Right now I have a GTX 550 ti. I was wondering if that card working alongisde either the i3 2120 or i5 2400 would allow me to play games like Guild Wars 2, Dota 2, TF2, Portal 2, Batman Arkham Asylum/City and Diablo III at alright settings (med/high) on a monitor with a resolution of 1900x1080.
More about2120 2400
i5 2400 Quad-Core will be decent help for the game play.
