I am an avid gamer and a full time student. I built my own PC and have a custom operating system that is a mix if Windows 7 Ultimate and a complete custom drive system, I made a compatibility to all Raedon Driving systems with catalyst control center. My PC's Specs are Intel Core i5, Asus Motherboard, and currently a AMD XFX R7770 Graphics Card.
I am wanting to upgrade my graphics card to a better one, but not fully sure I understand how the ratings on graphics cards work currently. I am a medical student, so my funds are REALLY limited. I want to say maybe $100-$150 is my budget to spend. If you have any knowledge to impart on me, I would appreciate it(even if it is out of my price range) or if you are possibly looking to sell something/make a trade/deal.
