Firstly, what is better prescott or Northwood. And secondly, should I turn the HT on I am using SX2 with loads of plugs, a powercore, a uad-1 and a Powerpulsar.
Building the box tomorrow.
Cheers Guys.

Northwoood is better at this stage, perhaps above 3.6 gig prescott will be better. Presently its hotter, a little slower, and a little dearer.
As to HT I did some testing in the weekend and found a turning HT off gave a marginal performance increase but the screen response was so bad that overall it was worse...this was in logic tho so maybee threads are addressed diferently in SX.
Just try it...it only takes a minute to tun of in the bios.

Is the Northwood really faster as the Prescott has twice the amount of L1 and L2 caches? Is this information based on an article you could link here or is this your own opinion?

check "toms hardware" or "anandtech"
most tests reach similar conclusion.

My understanding is that the problem is the deeper pipeline (and the heat of course). There are other improvements in addition to the increased L2 cache but these are mostly to offset the wasted cycles in the new core. Just like the very first P4 systems Intel probably intends to have a cpu is a dog at first but will scale nicely up to 5-6Ghz & beyond in terms of performance. It remains to be seen if they can fix the heat issues...
There are also larger changes taking place with Intel's line (ddr2, pci express, replacement for AC97, new form factor for motherboards etc) so I would tend to agree with others here that Northwood is a better investment currently. In a year that probably won't be the case and the currently emerging tech will either solidy and become standard or disappear entirely (the new mobo form factor doesn't seem to be well recieved and there have been fewer boards announced so far than expected, though oddly a lot of cases).

later in the year when intel ups the fsb to 1066 and officially suports ddr2 667.
the 720j chip with new stepping and temperature under controll, p4 4 gig PCIx PCIe...AND hopefully there will be some decent vidio cards that suport PCIe...somehow i doubt that BTX will have caught on by then.
then it will be time to change again.
