According to the HTPC hardware guru on the "other" forum the Celeron 1.3ghz is the biggest bargain at the moment & that a 1.3ghz celeron with the Intel 815 chipset (a-la the TUSL2-C ) still holds it's own against the P4's up to 2ghz.
The 1.3 Celeron cost's <55ukp
The newer 1.4 Celeron is going to be the last of the Tualatin cored P3's (intel is phasing out production) it costs <72ukp.
I'm going to "stockpile" a 1.3ghz Celeron until i can find a TUSL2-C or wait until you sell me yours......come to think of it...erm... all that i wrote above is rubbish the P4 is the way to go
You betcha...give me first refusal if you ever sell it
I've heard that dscaler 4 is very greedy on cpu cycles looks as if you will need the p3 celeron 1.3/1.4 it has 256k of on die cache or (seriously) one of the NEW p4's if you want to run the method you want with all of the filters used etc, also don't forget that dscaler 4 is only in ALPHA form at the mo the cpu overheads "could" come down.
