I just bought a Powercooler X800GTO and installed it into my computer for the sole purpose of getting good fps on Day of Defeat: Source. Previous to this graphics card i had a Nvidia PCX5900 and got roughly 20-40fps. I heard from a friend and multiple reviews that the X800GTO could handle source games on medium settings and easily pull off 60-100fps. I installed the new card and at first I got only 20fps. I did some tweaking and got it to run at 50fps with all the lowest settings but then after playing for a bit it dropped to 20fps. I have a Intel Pentium 4 with Hyperthreading. 1 Gig of Ram 200 gig harddrive Asus Motherboard I'd like to be able to play the game at least with a stable 65 FPS. Any suggestions?
