I recently decided to bite the bullet and change from Windows 7 and Arcade VGA to WinXP64 and ATI Radeon 4550 to be most compatible with GroovyMAME. The video card made my computer 300% quieter than the AVGA, since it has no fan. Setup was very easy. All I had to do was give the program the path to the MAME executable. It made an awesome difference, with all games running full screen now at the right resoutions and refresh rates. Well.. as long as I have triplebuffering on. I still have the same issues with inconsistant frame rates on certain games with TripleBuffer off. No matter what my monitor settings are. But the difference is so slight with TB on vs off that, I'm just fine with that.
The problem of course is Hyperspin. VMMaker found over 500 video modes and cut it down to 120, which I presume is the windows and ATI max. How many would I need to get down to for Hyperspin to work and how would I go about removing them? There are many video modes that I do not need. If I need to cut too many I may just have to use another Frontend until Hyperspin 2.0 comes out. (if it ever does)
Also when I ran ATI setup in VMMaker 1.3c (latest version I could find) it detected my card as a HD 4350 when it is a 4550. May not matter but was worth noting.
