I've finally gone PCI-E and have gotten my board and my video card. I've upgraded from an AGP 9800 Pro 128MB to the X800XL 256MB GDDR3. I'm having a terrible problem with frame rates. When I play regular ol' Half-Life 2 singleplayer everything is fine and noticeably better than my 9800 Pro. But when I try to do any form of multiplayer such as HL2 Death Match, Counter Strike Source, or even Garry's Mod my frames are 15 and below! I don't know what the problem could be. When I first installed the hardware and powered up my computer I remembered, shit! I didn't uninstall the old drivers from the old motherboard and graphics card. So, I uninstalled those drivers and replaced them with the new ones, I don't know if that could still contribute to the problem or not. And with the video card I didn't use the drivers on the CD, I just went directly to the ATI's web site and got the CATALYST 5.7 driver for Windows XP. Ok now, where did I go wrong? My computer is running fine, I think I made it clear i'm just having problems with my video card. If you need any other information say so, because I would really like to fix this it's impossible to play online with these frames!
