Hmm, 1GB of DDR, a 754 AMD 3000+ and a 1600x1200 res... thar your problem! You most definately need to upgrade your RAM. These days there is just no excuse for having 1GB when 2GB can be had for $40 or less! Upgrading your RAM should be your first priority if you don't plan on upgrading your CPU. Your CPU is simply just holding you back. I'm afraid you will need to upgrade. I'm almost certain you will get significantly more FPS even if you upgrade to something like an AMD 4400, and 2GB of DDR2. If you're still experiencing problems, then definately RMA your device. Like others have said you should not be getting artifacting though. Check to make sure your vid card is not overheating.
