^actually Toms did a article on the 805 because of its relativley cheap price, low power use and heat output (it was after all the much better 65nm Ceadermill Netburst CPUs) and they OCed it pretty high.
And with that OC, it beat a Athlon FX and Pentium D EE. Both $1K chips while the 805 was $125-$150 at the time.http://www.tomshardware.com/reviews/dual-41-ghz-cores,1253.html
At the time, this CPU cost a fraction of any of AMDs CPUs and was the best overclocking CPU thanks to its 20x multiplier.
So its nothing to sneeze at.
But for the OP, if you can get a Core 2, do it. if not then the Pentium D 805 would be better than a Pentium 4 3.2GHz.
