So lately I've been getting into PC gaming, and I'd like the right hardware. I've checked dozens of games on "Can You Run It" and the only thing I was missing on all of them was a new video card. Right now I have a Intel(R) G45/G43 Express Chipset. So, I'd need one better than that, obviously. My objective is to be able to play most games on a high/medium setting. Nothing super crazy. I'm tired of having to look at shitty textures... Also, how hard is it to replace a video card? I'd rather not destroy my computer. So, suggestions? Take into account that I know pretty much nothing about computers, much less the shit inside of a computer, so a little hand holding is appreciated.
