My Nvidia 8800 GTS XLR8 320mb died and now I'm looking to upgrade. I've found some gpu's on craigslist.com and it seems that someone has a RADEON HD 4850 for about $40 is it worth it to buy that? I bought a stupid 7950 gx2 and it seems that people say it doesn't support dx10 and 11 or something. I'm not much of a graphic card person but would like to play League of Legends and many other new games (doesn't have to be on ultra-high settings).
