the AMD Athlon XP line is a good budget processor. If you are going to overclock, u would want to go with a mobile XP. If i was you i would wait for the 6600GT for AGP. There are some pretty cheap mobos for Socket A. Just look around some websites like www.newegg.com or something.
Could I buy any new Proccessor, Would it fit my Motherboard, Same with my Graphics card....I just wanna find a better graphics card that will fit my mobo, and maybe a proccessor, and some more ram
there are different sockets for different processors. As long as you have am AGP 8x slot on your mobo, then u could use almost any graphics card. What mobo do you have?
