GroovyArcade (Linux) ATI graphics card support

[bernieke]

Hi,

If I want to run GroovyArcade (Linux) with a CRT monitor (27" Sony Trinitron with SCART) to play arcade games from all eras, which card would you recommend I get?
* a new Radeon R7 360
* or a second hand Radeon HD 4870/4890

I don't care about the price difference, it's pretty negligible considering what building this cabinet will cost me...

I see that according to videocardbenchmark.net the new R7 would provide over twice as much performance. (Which should help with any new games like SSF4 right?)
But will everything else (15khz, wide range of refresh rates, ...) work equally well as it would with a HD 4XXX?

Apart from that, how does GroovyArcade compare to Windows 7 with GroovyMame and the CRT emulation driver?
I prefer to run Linux (it's what I've been using at home and professionally for the past 15 years), but if it won't hold up to Windows for Mame emulation, I'm not adverse to running the cabinet on Windows.

This is the hardware I've selected so far to put in the cabinet, can you see anything wrong with my choices?
* fractal design core 1300
* g.skill 2x4GB F3-10666CL7D-8GBRH
* gigabyte GA-Z97M-DS3H
* intel pentium G3258
* samsung 850 EVO 500GB SSD
* Scythe Kotetsu CPU cooler
* Seasonic M12II-520 EVO PSU
* 27" sony trinitron CRT with SCART
* ultimarc mini-PAC
* 2 x ultimarc servostik with sanwa JLW
* 2 x 7 game buttons & player & coin + power with led

If you choose Linux, then maybe an HD 5xxx or 6xxx is a better option. Under Linux you're only limited by what's supported by the current open source driver. Not sure is R7 is currenly supported, and there no reports as far as I know. HD 5xxx and 6xxx are known to work, on the other hand. For Windows, there'll be support for 5xxx and 6xxx soon too.

Regarding Linux vs Windows, Linux wins in video flexibility, Windows wins in low latency input and hardware support.
