If you're friend owns a computer store, give him G2's specs and your computer. I vote for the P3 600, then a good 8x AGP video card with some extra RAM. Yes, XP is a RAM hog, and the added memory will help to compensate for XP, and give G2 better performance. Again, if you don't know too much about computers, ask your friend. There are many specifications that need to be matched for hardware to work together. Good luck, Andrew
