ok im getting alot of lag with my current GPU in the game Fear, even with it on low everything, except i have Dx8 shaders and pixel double set to off. i have a 6800 and i bought it from Dell. so im looking to upgrade to a better card, or fix this one. Im looking for a GPU that will play every game out on the market at this time and this coming winter on max settings. Im eying up the 1950xtx and are considering buying it. This is where my question comes in. Does the ATI 1950XTX work in a Dell XPS 400? If so let me know please. :)
