talking about price performance ratio
1.6 northwood is about the same price w/ XP1800+
it's around $130 at
Newegg I believe.
but the the XP beats northwood on the performance all the way{not OC],
I'd say about 30%, you can not get really high OC on XP probably about 1.7 on
XP1800[it will count as XP2000 on some mobo] - on the other side the 1.6 can
be OC to 2.2 easily or you can go all the way to 2.4 or more if you have a nice setup.
Now the performance becomes par, well more or less in a few aspect.
So if you will be satisfied with the stock clock speed take the AMD, it's faster on the same price
but if you will enjoy OC'ing than you have the choice.
I'd go with Northwood because I've been on AMD since the Athlon 650 and the
price of pentium is unbelieveble at that time, now when the price is seems reasonable
i give it a try, i had XP1900 that i had to sell it to get the northwood.
I 'm happy with my 1.8a@2.5/MSI845 now, it's not faster than
my XP1900@2000+/KR7A but at least it's not slower neither since
I don't spend extra money on this setup. The money I got from selling
the XP setup is the exact amount i have to pay for the Northwood.
