PC on a budget, I did a quick shopping list and then found some prices over at www.clubit.com (There may be better and cheaper places out there, but they had the right gear at what looked like the right price)

Taz-nz - thanks for all the helpful info in this thread.  I'm really not looking to replace my MAME machine, but was curious why you picked some of the components you did (I understand the theory, but not all the requirements)., and my budget is much less than $360.

    GIGABYTE GA-P35-DS3R Rev. 2.0 LGA 775 Intel P35 ATX Intel Motherboard Retail     $128.50Is it important to use this particular board, or just a P35 board.  For instance, Newegg has a Open box MSI P35-Neo2 FR for $65, or the Gigabyte GA-P35-DS3L for $90.  Club-It also has similar (slightly better) prices on P35 boards.
    Cooler Master RR-CCH-LB12-GP Hyper 212 CPU Cooler   $33.99I guess the cooler is pretty critical to stable overclocking, but $35 seems a bit high.  I don't know of good alternates, though.  I've like Arctic Cooling in the past (but that was on Athlon XP systems), and the new fanless towers (like Tuniq) look cool, but again not sure how they'd be for overclocking.  Any idea how the stock Intel cooler would do?
    Intel Core 2 Duo E4500 M0 Stepping Conroe 2.2GHz 2MB L2 LGA 775 Processor Retail BX80557E4500 SLA95   $123.50How would the E2140, E2160, or E2180 compare with this processor - they are all 800 FSB parts and priced at $70-$90.  (Also, some of these mention a particular "Stepping", but I don't know how this factors in.)
   CORSAIR XMS2 2GB (2 x 1GB) DDR2-800 CL 5-5-5-12 Dual Channel Kit Retail TWIN2X2048-6400$74.50I'm not sure 2GB is required for a MAME machine - Newegg and Club-It have 1GB DDR2-800 Cas 5 for $25-$35 and 2GB (matched pair) for $54.  Would this be acceptable?  Would DDR2-1066 offer any advantages?

If the pieces above would work, you could knock $200 off the price above and put together a system for around $160 (65+70+25)

Thanks again for all your help!!!

I have played with different memory timings and speed on my main computer and none of it does squat.  I went from 533 to 800 FSB and 4-4-4-12 to 5-5-5-15 and it only looks pretty in the Sandra graphs but MAME does not care.  I only cares for one thing: processors speed. 

The tests above where on a Core 2 Duo E4300 running at 2.4GHz.  I ran it at 3.0GHz for a while and the FPS did not quite scale linearly to 25% faster but to about 22% faster.  The games I was looking at were mace and umk3.

On my intended MAME cab machine (which I have yet to fully configure) I tried 384 vs 512 and PC100 vs PC133 and so no difference there either but I only benchmarked umk3, mvsc and garou.  I don't have enough evidence but I tend to think that you probably don't get added performance above 512MB of memory even for the larger neogeo games.  I don't know if this is the case with hard drive games because that machine will not run it at any decent speed so I did not even bother to benchmark it.

I suppose I will have to use an older version of MAME for umk3 and other of the more demanding games.  Luckily, I don't care for any of the hard drive games but, like I said a few posts ago, I'm out of luck for SFIII.

metahacker:

can you try a comparison to your regular benchmarks with the following in your Makefile ARCH= line ?

-march=nocona -mtune=nocona -minline-all-stringops -maccumulate-outgoing-args -mmmx -msse -msse2 -msse3 -mfpmath=sse -funroll-loops -fomit-frame-pointer

and perhaps even compare that to

-march=pentium-m -mtune=pentium-m -minline-all-stringops -maccumulate-outgoing-args -mmmx -msse -msse2 -msse3 -mfpmath=sse -funroll-loops -fomit-frame-pointer

Ok, i finally have my mame e6750 w/vista 64, 4 gig ram running on mame, 121.1, carnevil & mace run perfect, Gauntlet legends & blitz run good but they still have a slight sound jumping.  Taz how does blitz run on your 6850, & 121 have you noticed a slowdown if so i may go back to v120.  thanks for the help also i overclocked to 3.4

When I compiled this list of parts, I wanted give people a good starting point I knew would overclock well, so I went with parts I deal with on a daily basis.

Any P35 chipset board is a good start, but they are not all created equal, the Gigabyte P35-D** series of board are proven overclockers, and they use better quality parts, see Ultra Durabilty 2. The GA-P35-DS3L should be fine stay away from the GA-P31-DS3L the chipset is rubbish. I'd stay away from the MSI unless you can find plenty of proof it's a good overclocker, I not a fan of the brand they fail to often for my liking. (The main reason for going with a P35 chipset board is that they are very stable at high FSBs which is very important when overclocking, extra cooling of the northbridge doesn't hurt any)

You really need the heatsink if you want to get any really good overclocking results, the factory heatsink is overkill for these CPUs out of the box, but soon fails to keep up as you start to overclock them. There are plenty of good coolers out there, but currently the Hyper 212 is the best value for money as far as I'm concerned, it's performance is only slightly below that of theThermalright 120 Ultra I used in my system, at about half the price. There are loads of coolers out there that don't live up to the hype or their cost, the Hyper 212 just gets the job done and is affordable.

The E21** series overclock well like all the Core 2 Duo, but the 1mb cache has a noticable effect of their preformance when compared to a E4*00 or E6**0 series Core 2 Duo of the same clock speed, they are also limited in most cases to around the 3ghz overclocked from what i've seen, with a few managing 3.2-3.4ghz. The E4*00 series processors, are more likely to hit the 3.2-3.6ghz mark and have the large cache which helps their preformance.

I choose the E4500 M0 stepping as the 9x multiplier means you only need overclock to 400mhz FSB to get to 3.6ghz, and thus you only need DDR2-800 memory. The M0 stepping is the same as the G0 in the E6*50 series processors, these stepping overclock better than the older steppings of Core 2 Duo, and thus are worth having if your looking to hit big numbers. (steppings are small changes made in the CPU design to fix bugs or increase production yeilds, they tend to optimise the design toward stability and some make for great improvements in overclocking.)

2gb is not a must for MAME, but the catch is that the best OS option for mame Preformance is Vista 64bit which is a memory hog, and really needs 2gb to run well, to give you an idea, while doing some of the CPU only benchmark up to 1.7gb of physical ram were in use, and that with nothing running but Vista and MAME. Windows XP 64bit might be easier on the memory usage but is not as well supported as Vista 64bit, and you can get Vista Home Prem 64bit a lot cheaper & easier than you can XP Pro 64bit.

In regard to ram speed I really haven't seen much difference in MAMEs preformance when using different preformance memory, but make sure you run dual channel no matter how much memory you run. Any half respectable DDR-800 ram will do just make sure it's compatible with the P35 chipset, there are a few Dimms out there that work great on the older Intel chipsets and with AM2 CPUs but are totally unstable withe P35 chipset.

Preformace is just a question of money you have to ask yourself how fast do you want to go, and then speed the money need to get their. To give you an Idea my system for CPU, RAM, Motherboard, & Heatsink cost around $1300 NZD and number of months planning and saving.

Hope this helps fills in some of the blanks for you.
