Hi all, I currently have an Intel Core 2 Quad Q6600 2.4ghz, 4 gb memory, 500w ps. My graphics card is a BFG 8800 GT OC 512mb. I wanted to upgrade to a new card so I bought the EVGA GTX 550 Ti 1024mb as it was in my price range. However, the game I was mainly upgrading for (BF3) was very choppy and kept locking up as I was playing. I went to EVGA to dl latest drivers and did a clean install. No change. even my regular Windows environment seems to hesitate a lot as I switch windows and run programs. Put my old card back in and am running the game (and Windows) smooth(er) again. Both cards were running at 1900x1280 resolution. The old card is several years old so I can't understand why the new card is running so terrible. The specs just seem so much more advanced, yet... Anyway, any advice is greatly appreciated as there are some great games coming out and I wanted something a little better than what I have.
