Well actually I used to build Athlon II X2 systems for dirt cheap, for my relatives that just use their PC for internet pretty much. But since the E3200/E3300 wolfdale celeron's came out, I switched to intel. I had an Athlon II 245, it overclocked to about 3.8ghz max on air. The E3200 I got to 4.2ghz, in fact it would clock to 4ghz on the stock cooler, that last 200 mhz really needed more voltage. And now, the E3300 is just $3 more (was like $10 more when I bought the 3200) so you get an even higher multiplier.
