thanks... some more questions... first of all i dont understand something... AMD has a 3000+, 3200+, 3400+, etc. i know that those numbers tell the equivalent to the clock speed of an intel pentium 4. but how can these processors differ in speed if some are the same clock speed? for example the 3000, 3200 and 3400 are all 2Ghz.. but they are different prices and obviously different speeds. the other question is how do i know which socket i need?
