4Ghz Core 2 Duo vs M.A.M.E. 0.120 (benchmark results)
MBaran:
If the 2nd core is only accountable for ~5% increase, could a P4 or Pentium D at 3.2 - 4ghz, not provide the same results,within the 5%?

No, one core of the CoreTM2 is about twice as powerful as one core on a P4, as far as mame. IOW, you'd need a 8Ghz P4 to match a 4Ghz C2, solo or duo.
Ghz is like RPMs is to a car: a higher max RPM engine only means a faster 0-60 if the engines are the same otherwise. And the CoreTM2 engine has twice the horsepower and torque per RPM as a P4.
BTW, I hate intel's generic brand "CoreTM". Especially in topics like this where one vs two core & pentium or athlon vs CoreTM are discussed.

No, the Pentium 4 and Pentium D and based on the "Netburst" architecture, the Core 2 Duo is based the "Core" architecture, the core architecture does almost double the work per clock than the Netburst architecture. Because of this a Pentuim 4 would need to be clocked at around 4.5ghz to match the preformance of a Core 2 duo at 2ghz.
The Netburst architecture behind the P4 was a bit of a failure, It was slower than the P3 architecture at same clock speed at launch, didn't become competitive until the P4c 800fsb HT version lauched with the 865 chipset, the large cache of prescott P4s was nothing more than a band aid fix to a failing CPU design. The Pentium D was a rubbish CPU up and down, from day one it was total out classed by the Athlon64 X2, The Pentium D has hot, power huggry, noisy, and expensive, all things the Athlon X2 was not, and the Athlon X2 was faster in 95% of tasks, how Intel managed to sell so many Pentium D cpus is beyond me.
The Core 2 Duo is the only CPU currently able to jump the MAME preformance gap.

The E8400 OEM's are back in stock and I plan on ordering and overclocking a machine based on Taz's recommendations. I don't currently have a case. Can someone make a recommendation here on what features I should look for?

The Coolermaster Centurion 5 is a good option and can be had fairly cheap, there is a version that comes with a 460w power suplly that is passable for the kind of hardware your likely to have in a MAME box.
There are plenty of other good cases out there, anything with good front to back airflow will do, avoid cases with doors, solid face plates, or that have dozens of fans pointed in random directions.
