Hi all- Got the AsusFX6300 stock and need a better graphics card, although impressed with the performance on this rig as stock. I was thinking about another AMD card, newer and money isn't going to stop me under 400 bucks.. that is, and also only interested in as much card as my system will support(i.e not looking to put a V12 Titan into a VW Beetle). Suggestions? Also, beneficial to take ram up to 16g when I do this? I'm at 8.0 now... Thanks for your answers!!
