MY budget is around $200. I don't really care much for a high resolution. 1680x1050 is good enough for me. :]
He's not asking what resolution you'd like, but what you have. What is your monitor resolution?
To answer your question, $200 will buy you just about the best card on the market. This, of course, if you don't care that it's used. I would look on a P2P exchange site like eBay or craigslist for a used card under $200. I bought my GIGABYTE HD 6870 for $202 on eBay about 2 months ago. It's clocked at 920/1090 and shreds every game out there.
