The 3200+ has a faster clockspeed then the p4 2.8 ghz cpu.. but think about this..
the 3200 runs hot, no matter what heatsink/fan you have, unless its a watercooling device, it will run hot(ter) then the p4.. if yyou try overclocking a 3200 significantly you will either burn your cpu/mobo/ram or get dangerously close to it.. Now, with a p4, you can overclock from a 2.8 to 3.4 with minimal heat increase..
so the result? 2.8c ghz northwood ht cpu overclocked to a 3.4 ghz and now runs faster then the 3200+ AND has equal or lower temperature readings.. lets not forget hyperthreading if you want it enabled, and higher FSB speeds.B]
