Hi,
Yes that monitor handles 15Khz, so you could go native res. Note that the high resolution of the monitor means the games will still look a bit "too good" compared to a arcade monitor, although with that size, the dot pitch is probably quite large...
Only thing to check is inputs - does it have a VGA and a RGBHV input, or just the RGBHV? ie, is the full input range (15-82Khz) achievable from a single input? (I believe it is with that monitor - but worth checking).
Only other thing of note - you mentioned high res PC gaming. I am not up to date with the current ArcadeVGA chipset, but they tend not to be cutting edge (last one I saw was based on a 9200 Radeon - no slouch, but does not cut it on newer PC games at high res). I think there are newer ArcadeVGA's out then.
Your other option would be using a normal gfx card and using powerstrip to create custom 15Khz resolutions - but this is a LOT more work/fiddly.
