I get to test things like this out, in the place where i work, and this is one of the ones I tried.
SO I can give you some 1st hand knowledge, I tested these 2 systems against each other, overall performance differences in speed, is not noticeable enough to matter much, The Amd performed better in certain games and programs and the Pent 4, outperformed in others.
So it comes down to basically price, whichever is cheapest is the way to go, as you will get more bang for the buck from the cheaper of the 2, you could try 50 games and programs and these 2 may split in half the number each wins the race in.
So whichever you like best or the cheapest if money matters most for you.
Both are solid, fast and reliable.
