OK so Christmas is coming up fast and my card seems to be dying. I get a lot of artifacting now and the monitor will stop receiving signal and then starting receiving it again a few seconds later. I currently have a Radeon HD 6850 and need to upgrade anyhow. I am looking to stay under 200 dollars if at all possible. I want something that will out perform the card I have now of course. I do not care between Radeon And Geforce. Either will do. Can someone give me some tips on some cards that will or might be in the price range by that time? I do gaming....From Call of Duty to various other games. Some demanding games as well. Any help would be appreciated.
