Ran prime95 for 24hrs no problem. Never crashed. However, I can only run doom3 @640x480, anything higher is choppy.🙁Should I upgrade video card?????
Help,help,help
 
Do you have AA enabled in the game or the BIOS? It's very likely this is what is killing your performance (turn AA off!)

Also, what video mode are you on? Low/Medium/High/Ultra ? You should be on High, but not Ultra.

What version of drivers are you using? The 4.9 Catalysts have big improvements over previous ones. However, if you are getting bad performance, maybe you have lingering files from old drivers. If you did not just clean format and install the Catalyst 4.9's (ie you have run a previous driver set before), then uninstall the 4.9 Catalysts, run Driver Cleaner and get rid of everything "ATI" and then reinstall the Catalysts 4.9's.

Have you tried increasing the "cachemegs" in the Doom3.cfg file to 128MB or 256MB (from the stock 32MB setting)?

What is your memory like before you open Doom3? Should be about 350-400MB free; hopefully nothing big is running in the background.

What is your 3dmark 2k3 score, and is it choppy in other games?

Is AGP 8X enabled in the BIOS?


Let's hope to god you don't have one of those crippled 128-bit memory Sapphire 9800 Pro cards...


Check through these suggestions; the solution is probably one (or multiple) of these.
