Buying a new comp.I can afford about 1500.00 and wanted 2 know what 2 buy. P4 or AMD? are 64bit processors over rated? Radeon or GeForce? 128 -256? Hardrive size? Should i run 2 or is 1 o.k? I only play games like Il-2, F1 racing and call of duty. I don't want to spend extra dough if i don't have too. Right now i have a 1.6 P4 so any things gotta be better!!!
