Hi again Nestor
The 2.4GHz 800MHz FSB P4 is out now, and it is not priced too far above the 533MHz model. Also it does support hyper threading, and considdering that you will have this PC for some years, it may by worth going for. Who knows, if the next version of your music software takes advantage og HT - or the version, that will be released in 2 or maybe even 3 years?
If you want to take advantage of the 800MHz FSB, you will have to pick another mother board though. You have desided to buy a new PC at a moment with a lot of new things comming in. I know, this is the worst answer to a longing soul, but if you wait 2 or 3 weeks the market may be much clearer, and prices
may have dropped a bit too - both on the new stuff, and on the stuff on your list (because it will be then be "old" stuff).
The "I think you should wait a little" answer is extremely rare from my mouth/fingers. New stuff is always comming in, but at this very moment a lot is happening. Waiting 3 more weeks may give you as much as ½ a year before you will again want to buy a new PC. You will get:
Hyper threading <-> no Hyper threading
800MHz FSB <-> 533FSB

The benchmarks may not reveal a very huge advantage, but you track bouncing my guess is, that you will feel the difference. Also, and this should not be underestimated - if you are just a little bit like the rest of us (most psycologiacal "functions" are not as unique, as most people like to believe), in 3 years time, when your PC is not that new anymore, you will feel different quite different with having 800MHz + HT, than you will feel with having 533MHz - HT. Psycology is part of my study, and I have moderated a hardware forum for 1½years. And I highly believe in this psycological factor.
I don't remember the last time, I told somebody to wait - if it has happened, it probably was in the late summer 2001 when the ECS k7s5a got extremely good tests paired with a very low price (it is not fast by todays standards, but back then it was pretty amazing). I usualy tell people not to wait, because waiting for hardware can take forever - there is always something new comming next month.
You can get a 2.4GHz 800MHz FSB system today, but everything is in a very early stage, and the situation will probably be much clearer within 3 weeks. Also prices are very new right now, and will by good chance drop within that time. Not least important - there may be new BIOS-versions comming out, wich may turn a loosing motherboard into the leader of the pack.
Did I say, that I think it would be realy good, if you could sample all your patience, be strong and wait just 3 more weeks?

I wich you the best Nestor, and I will by any time try and support you in making your own disition, I just have this feeling, that you will be very happy waiting 3 more weeks
Ok, I stop it now, I think I have used my bucket of .... what was it the bucket is empty .... did I use them all already? .... something with time .... ?
