About a year ago I upgraded my 10 year old CRT MAME cabinet which is based around a 27" Wells Gardner D9400. The "right" CPU/GPU combo depends on what you want to emulate. Previously I'd only run GroovyMAME on that cabinet but after the upgrade I wanted to add some other console emulation targets, mostly Sega Genesis / Saturn but possibly a select few PS2 / N64 / DC titles suitable for Arcade cabinet-style play.
Here's the system I went with:
- CPU: i5-4590 CPU @ 3.30GHz / 8GB RAM / SSD + HD / Win10
- GPU: ATI R9 380X OC (factory overclocked version)
I bought a used HP ProDesk 600 G1 on Ebay with SSD boot drive and Win10 Pro pre-installed for ~$120 and added an HD I already had for ROM storage. The 380X GPU is the *
last* & fastest card ever made with an analog output (which is only on one of the two DVI connectors). They are somewhat rare but I found one for $100 on Ebay, a bit steep for this era of card (2016) but I wanted to get the max possible GPU power to 4x upscale a few 3D PS2 titles to an internal res of 1600 x 1200 for analog display on the D9400 at non-interlaced 800 x 600 @59.94fps - while keeping that visual retro magic only an analog component signal on a quality multisync RGB CRT can give.
Note: The 4GB RAM R9380x (2016) and the earlier 3GB RAM R9 280x (2014) are nearly identical in performance (2013-2016 was a weird era in Radeon evolution), so those looking for the best analog output card ever made can choose either one. The 280x has the advantage of a wider memory bus (384 bits) but runs hotter, while the 380x (memory bus: 256 bits) has the advantage of the more recent Tonga / GCN 1.2 architecture with texture compression and faster tessellation. This works out to be within a few percent in FPS depending on the game according to reviews published at the time (380x +4% to -2% vs 280x). Also, be aware the similar-sounding 390/390x cards can cause confusion because they were faster than the 380x and 280x but didn't have analog out (despite some product spec listings erroneously saying they had DVI-I, actual photos of their DVI connector reveals they don't have the extra four analog pins and are thus DVI-D (for digital-only vs "DVI-I" for both analog & digital). The 280x and 380x both look like this:
But the 390/390X look like this:
