If you are asking if you get a new Socket A system to replace your old one and get an XP 2500 CPU to replace your old Duron if you'll get a nig performance increase, the answer is YES.
For several reasons.
1) Newer, faster CPU.
2) Newer, faster RAM (your current setup uses PC133 RAM)
3) Newer motherboard with better features.
Again, if you need more info, you will have to be more specific.
XP2800+, Abit NF7, 1GB Dual-Channel DDR333, ATI R9800PRO 128MB, TT PurePower 420W, LG DVD+-R/RW
