Pentium IV-3.06Ghz 533FSB 512K HTPentium IV-2.8AGhz 533FSB 1MThese are your only 2 choices. I have heard that HT can cause problems in some games. Also, the 1MB cache, would that counter the loss of 200MHZ on the other CPU?See you in the fence...CYYZ

I've never seen any problems with hyperthreading on my PC (other than that the CPU is about 3-4C warmer with two threads running maxed out), but I've yet to see any evidence that FS2004 benefits from it... so in that case they'd probably be pretty similar where FS2004 is concerned.I'd be tempted to go for the 3.06 just because it's going to benefit you in general any time there are two or more active threads on your machine, not just for FS2004.

If those were the only two choices then I would have to say NONE of the aboveFirst off ... the Prescott (Revision E) is a flame throwing dog. Wasted 6 months waiting for it to come out ... yea yea the 1 meg L2 cache and all looked real nice. When the CPU came out ... No obvious improvement in anything..(Intel added 10 more stages to the pipes) so the enhancements amout to nil at the moment. But theres an obvious heat output increase. For the processor speeds you are referring to. I would suggest you get a P4 3.0 ghz Revision C (Northwood) ... And if hyper threading is bugging you .. you can turn it off from the bios Although im running a 3.0C with Hyper threading enabled with no probs.and as for the Pentium IV-3.06Ghz 533FSB 512K HT (Revision :(... Its good ... but...your missing the 800mhz fsb 2x4 quad pumped. A tad on the old side..but its the lesser of the two evils.

Yes the Prescott was a huge failure on Intels part. From what everything looks like they won

hi altstiff,if you can get your hands on an 850E chipset mobo. and the 3.06 CPU with PC1066 RDRAM then get it. your not missing anything with the 800 FSB mobos. ole DDR memory can't hang with the faster RDRAM. wish i still had my old 850E based mobo. happy flyin, fm
