I suspect that the onboard video would work ok. If not it's a simple upgrade.
One thing I noticed is that those "3D" games seem to run faster in some older builds of MAME. Specifically, I was messing with some different versions on my workstation (dual xeon 2.6Ghz) and 0145 seems to run close to 100% on Blitz and Gauntlet DL. Where as 0152 only runs at about 80%. Again, this is just an observation. It's highly possible that some other program or task was using up CPU. Also, I noticed that 0152 seemed to run close to 100% on my i5 (sandy bridge) running at 4.5GHz. However, there are still some dips below 100% and occasional sound glitches. So, I suspect that you'll run pretty much everything just fine, but may get some minor stuttering in the "3D" games.
Again just some observations, so you MYYV.
