Athlon XP1900+ (1.6GHz)
1GB RAM (this is however 512MB Samsung PC3200 and 2x 256MB generic PC2700 RAM)
I'm not looking to spend a great deal of cash on this, maybe say £100 or so. Was looking at a Radeon 9800SE 256MB on ebay which was about £30. In terms of upgrading the processor, I'm not certain but I think the highest I could go to is a 2200+ but this is only 200MHz quicker than my current one I believe (?)
I guess my real question is if I get the above processer & GFX card and maybe swap the 2x 256MB sticks for a new 512MB stick of PC3200, how much of a noticable increase in performance would I get?
