Right now, my brother has this
Compaq Presario SR5110NX
and have this motherboard in it
Except that we added another 512mb, an 7300 LE (I think), and changed it to XP. The mobo said it supports X2 4800+ up to 65NM, but problem is that I don't remember what my old CPU was, I know it's an X2 4800+, but don't know how much NM. How much would it make of a difference between that single core compared to my X2 4800+? Also, would you guys suggest we take out those 2 512MB and buy 2 1GB DDR2 ram? All he uses it for are just web browsing, music, and video. For XP, I think 1GB total would be enough, but what do you guys suggest?
