I have two computers and they both have GT520 video cards. One computer uses an AMD FX 6100 as a CPU. The other computer uses a Intel i5 2600. I want to play Company of Heroes 2 and was wondering which rig should I use and what kind of video card upgrade will allow me to play the game with high settings. I use a 1400x900 monitor. I can stand to spend $250-$350 for the new video card.
