3D Game Performance in MAME

I've only got a Dual Core Celeron at 2.4 Sandybridge with Intel HD3000 onboard GPU and even that handles 3D no problem at 1920x1080, 8GB Ram, Win 7 x64

I am not sure I agree with that statement for the following reasons:

1.  Several current quad-core offerings (eg. i5-2500k) can be overclocked and can run two of their four cores faster than your i3 can.  With these chips Gauntlet DL and SFRush are playable with no issues.
2.  My i5-2400 runs Blitz @ 100%, but in doing so all four cores are in use at well over 50%.  This means one of two things:
     (a) Mame is fully utilizing 2 of the 4 cores, and a number of non-mame tasks are being run on the other two cores, bringing the overall usage to above 50% (which supports having more than 2 cores)
     (b) Mame is using more than 2 cores.

Hmmmmm.....interesting Diet Pepsi.  I get what you are saying so I double checked on the mamedev site FAQ section.  I could swear that about 2 years ago when I read through there it specifically said that MAME could only utilize 2 cores.  Well it's not there now!!!!!  It does mention multi-core systems but does not get specific.  Technically 2 cores is multi core.  I know they are making progress all the time with MAME so maybe I have to retract my previous statement?? Does MAME now use more than 2 cores?? Sounds like it might.....

What's the fastest processor that will work with your mobo?

From my experience, Killer Instinct should be running full speed or close to it with what you have, and Tekken stops having sound skips around 3Ghz.  You need a lot more than that to run Blitz.  Using a 64 bit OS and MAME64 makes a big difference for certain games, Blitz in particular.
I always use Black Viper's guide to disable all services that aren't needed, including networking.

I'm still using xp32 on my main setup because I have some accessories that 64 bit drivers don't exist for.  It has a 2.9Ghz Athlon X3 and runs Tekken full speed, but IIRC, for Tekken 3 or Tag, I'm running a clone that ran faster.

I've run similar Athlon X2 and Athlon X3 processors and believe the third core does make a noticeable difference.  Presumeably by handling overhead.  I settled on 3.4Ghz Athlon X3's as the budget sweet spot for my driving cab and current build. (I buy stuff piecemeal from Newegg when I see a component cheap)
I'm not really recommending AMD here, they were just the best value at the time.   I'd fork over the money for an i5 if building today.

Just had a run with Blitz on my new cab that runs a 3.4Ghz X3 w/Vista 64 (for DirectX11).
It's fully playable, but has some slight sound issues. 
There are some Shmups that don't run full speed in Demul.
Most of them run full speed using Makaron, but a couple of them feel like they need a few more Ghz.

It always irks me when people steer new builders toward processors too slow to even run Tekken.

Good info guys. I've had to stick with 32bit because I had problems with the video card drivers working, but I may try and revisit it.
