Hi all....hoping for some recommendations. I've recently purchased a NF7-S motherboard, Thermalright 900U heatsink and 512MB of Buffalo 3200 CH-5 RAM. Question is, what cpu should I purchase? I'm not sure if the RAM I've got will allow me to overclock alot or not? I've built some computers before but never really considered the overclock(not necessary with this computer but would be nice I suppose). Could someone please advise if I should go for an unlocked/locked Barton, mobile Barton, 2100+ Thoroughbred, or whatever else? I've got about $115 to spend. Thanks....
