P4 Wasn't crap, the architecure may have been inefficient per clock but because of the clockspeeds they were still just as fast as amd's.
With any normall cooling they all hit 4 ghz on air, the prescotts anyhow.
A 4ghz pentium D for example would be just as fast as a 2ghz c2d, wich is erm, between an E6300 and an E6400 in, although overclocked they wipe the netbursts ***, a board that clocks well for a c2d is at least 50 quid, while for p4's its 15 quid ( yes early 2nd hand lga775 boards are rly that cheap). The base price of a c2d is also a lot higher, you can get a 3ghz pd 925 for 50 €, while you need to spend at least 75 € for an e2160 or at elast 125 € for an E6400.
Prices evened out these days, you can get reasonable performance per buck for nothing these days with p4's, they are not crap at all.
Although I agree, c2d's are far superb atm, love the E6400 I have, but you can all in all get a twice as slow system with netburst ( wich is fast enough anyhow for vista etc, my old 925 @ 4ghz got a cpu score of 5.2 in vista, and scored as high in benchy's as people running E 6400's @ stock), for almost 3 times as cheap.
Tbh I dunno why a non gamer/ proffesional video editor ( or whoever that uses more cpu power than your average Joe) would have a true need for a c2d, a p4 is more than fast enough, same as a socket A athlon.
Hell, my dad used a p3 800 mhz for years even though he sells pc's, he just didn't need a quad core for micrsoft office, email and internet.
