I've got different responses from people in regards to this question.
To begin with I'm running a computer with XP Pro, MSI KT4 Ultra motherboard, MSI nVIDIA FX5600 (FX5600XT-TD256) video card, and a Sound Blaster Live 5.1 X-Gamer sound card. I have recently upgraded the processor to a AMD socket A 1800 from a 1500 (I know it's still a dinosaur). I've tried the 3DMark test and this computer got a score that was so bad that I forgot it. I know the motherboard will accept a AMD 2800+ processor, I just waiting for one to come to the store.
My main question is about memory. I have DDR333/512MB (1 stick) installed. Will having 1GB help any? The game that I seem to not get enough of is Unreal Tournament 2003. If you have any further comments that would be of some help please reply or send them by email. Thank you.
