The ideal pc
IG-88:
Sorry to drag up an old thread. Was just wondering why/if wbasset's HT cpu would work better than a dual core cpu? Isn't the HT is basically faking what the dual core is actually doing? So neither one really helps with emulation like mlalena said, correct?

Wbassett doesn't say that the HT CPU is fast than a Dual Core, he say the 3.2 HT is noticably faster than his 2.6.
It had to know without know the exact spec of the two systems, but I'm willing to guess the his 2.6 CPU is an early Pentium 4 with a 400 or 533 FSB running on a 845 chipset with single channel DDR 266. Where as the 3.2 HT will likely have a 800 FSB and dual Channel DDR 400, the Pentium really didn't become a good CPU until the 800FSB HT models were released along with the 875 chipset & 865 chipsets.
Clock for clock the older P4 system (presuming it's not a Celeron) would have no hope of keeping up with the newer HT P4 system, add in the 23% clock speed advantage the HT P4 has and it's no contest. While the hyperthreading probably does little to speed up MAME itself, it does help if you have a lot of rublish running in the back ground, by allow MAME skip the que instead of waiting for back ground task to finish with the CPU.
MAME preformance scales linearly with clock speed so straight away the MAME preformance on the 3.2 is going to be 23% better than on the 2.6 before you take into account the other advantages the 3.2 system has. So it probably has little to do HT and more to the system as a whole.
Early versions of MAME gain little to nothing from Dual Core CPUs, the current versions gain a huge amount of preformance when running on a Dual Core, this is most noticable on those ROMs with multi threaded drivers.
If you want MAME to run fast get a Core 2 Duo and overclock it.
Blanka:
It's not only Ghz, a 2ghz core2duo single core is faster than a 3ghz P4. Core2Duo optimized more than just putting 2 chips in one.
The E8400 is still very much bang for the buck, and I like the 9500GT for graphics. It's about the fastest card without extra power-supply cable, so relatively cool.

Thanks for the answers guys. Another question then,

Would a quad core save the trouble then of overclocking?
The reason I'm asking about this is because all I've ever really wanted to play is the early classic stuff but I've had some friends ask about the CHD games and I thought I'd build a fairly budget cab for that purpose. Without putting alot of time or $$ into it. Something I could just "slap" together hardware wise.
All I really need is CPU and Mobo recommendations. And I guess a vid card.
@Blanka: I will check out your suggestions later on.
