I am currently running a Nvidia GT 240 video card which I've had for about 3 years. It runs my older games well but is quite dated for games like Total War and such. I was thinking about getting a video card like the EVGA GTX 650(perhaps ti model), or the 660. I'd say economy for me goes around $200. I don't know much at all about this crap so I need help. Which video card would be the best bang for the buck? Would they run a game like Shogun 2 Total War well?
