Intel vs. AMD (MAME Emulation)

I believe you can compile your own version of mame to add support for more cores.

Buy Intel and you will not be disappointed.

No,  Mame won't really use 6 cores at this time,  and doesn't really do much with 4 cores.  I'd recommend going with a 2600k Sandy Bridge or it's Ivy Bridge equivalent if you want to play 3D era games.  I would only recommend AMD if you aren't going to play anything from the 3D era.  If you do want to play 3D era games,  the Intels are a much better choice.  For reference,  my 2600k naturally overclocks to 4.3ghz stable,  and runs all but the most challenging drivers at 100%.

This. Mame does in fact already utilize multiple cores - especially on the 3D games.  If you want currently-playable 3D games running 100%, you want Intel quad core running at a minimum 3.3ghz (MAYBE 3.1ghz, I haven't tested...) across all four cores.  In other words; i5-2500K at stock speeds, or better.  Check your turbo boost frequency tables here and here...)

I would say if you really want to give yourself some CPU overhead, wait until the Haswells are released in June. ~10% CPU increase over Ivy Bridge (+10% more over Sandy), a lower overall TDP, significant iGPU increase (my 2500K already runs PS2 emulation near perfect), approximately same price as current Ivy Bridge... and you can do the math yourself. Even I'm planning on upgrading, and I've NEVER done that so quickly between generations!

I've actually been researching things to get a handle on whether or not to upgrade to Haswell,  and my research has indicated that Ivy Bridge is only a situational improvement over Sandy Bridge.  If you look in the charts c0dehunter linked up higher and navigate to the 2012 ones,  Sandy Bridge and Ivy Bridge show largely the same performance.  From what I've read,  Haswell's only a 5%-15% increase over Ivy Bridge,  so I really think it's a pretty huge expense for a small gain.

That said,  if you're using the on-die GPU,  then it's a no brainer,  Haswell is the way to go.  But with a discrete card,  things get a lot more muddy from the information currently available.

I appreciate all the replies. Also, considering this is a build-on-a-budget, purchasing an Intel CPU at this time is not in budget, as I'd also have to purchase a new MB (I already have a compatible AM2/AM3 MB that I got for free). With that said, I've decided to go ahead a hold off on buying one at this time, at least until I'm further along in the project and can see a light at the end of the tunnel. There are many moons that need to align before this project gets even close to being completed.

What c2d do you have lying around?  Depending on what games you are looking to play that cpu may be able to handle the job and save you some cash.

I was looking at the 1045T X6 and the FX4100 X4, as my MB only supports up to 95w CPU's. My c2d is a 2.2ghz w/ 2gb of ram.
