Hi, I'm servicing my aunt's old Win XP machine and after making some nice upgrades to it (brand new Corsair 450 and Noctua fans) it's still dog slow even with maxing out the ram to 2GB. It's an Athlon XP 2000+ on a Jetway V6DP motherboard with 'Savage Pro 3D' graphics acceleration only, so my question is: would installing a GeForce 6200 AGP card help speed up the OS at all, or would there be little difference? Further to that, I was looking at a 512MB card but would a 256MB still give a good boost (if at all) to the system in general? She only uses it for the most basic of tasks and one Mahjong game in particular so I was only interested in speeding up the system itself, not anything for gameplay. Thanks.
