The modelines for Galaga and MK2 are correct, so you've got everything right.
- Galaga runs slow because we can't make a 15-KHz modeline with 288 lines that works at 60 Hz, we only can get 51 Hz or so, so when vsyncing the game's speed is reduced accordingly. If you wan't to run Galaga at 100% speed create an specific ini for it and add the option -triplebuffer. Bear in mind that you won't have smooth scrolling as the refresh will still be 51 Hz.
- MK2 modeline is right but you only get 98% speed, that's very probably a CPU issue, I'm afraid.
As for the fact that these resolutions don't fit the screen, you probably need to get more accurate monitor_specs. If other resolutions are fine, then you need to define a subrange for the odd ones were the right margins are defined. There are several threads in the forum were this is explained. You need to use Arcade_OSD, tweak some modelines and use the values obtained to create new monitor_specs from them. Not too difficult if you know what to do, but it requires some patience. However, not many users go that far, but at least the tools are there for any one.

Thanks for the help so far.
My CPU is a AMD|ATH II X3 455 3.3G AM3 RT. My thinking is that processor is plenty fast for the likes of MK2. I am having issues with a host of a number of other modern games as well. MK2 ran along with others such as KI and KI2 just fine when ArcadeVGA3000 was installed, so I am not sure it is a CPU issue. Maybe I need a higher powered graphics card?

The graphic card does not make any difference for MAME performance, this is a fact.
You need to distinguish among reduced speed due to refresh restrictions and genuine underperformance. This is pretty obvious once you have some experience but may confuse at first.
Always look at the logs to see if the calculated modeline has the desired refresh or this is lowered to accomodate your monitor specs.
If you have the right refresh and still can't get a particular game to reach a rock solid 100% speed value then trust me when I say it's a CPU issue. I don't necessarily mean your CPU is not fast enough, it may be some undesired task running in the background or something.
Keep in mind this: by default, GroovyMAME runs all games with v-sync enabled, as this is the reason of its existence. Running a game v-synced means you need more CPU power to run the game fluent than what's strictly required to run the game without v-sync.
Also, the speed value obtained in the logs may sometimes be unaccurate. Better press F11 when in game and check the figure shown in the screen.

Ok. Thanks for the info! This should be the last question.
I think I see what you are saying. I understand that raw processing speed is a constant, and particular games in groovymame require larger amounts of processing power than what would otherwise be necessary due to enabling of vsync. If the monitor specs are more closely matched and all other programs running in the background are shut down, will my CPU be able to handle almost all games with vsync enabled? What other CPUs are people using to play the MKs, Street Fighters, etc in Groovymame? 98% may be the mean calculated refresh rate - I can live with that, but when it runs, it will do a fast forward and slow motion sequence with the audio following along. I have also seen it run at 400% when I didn't adjust the monitor_specs correctly and I saw no screen tearing whatsoever, so maybe it is somehow capable of running at that speed.
Is there a how-to guide on adjusting the monitor_specs somewhere?

MAME runs much, much better on Intel CPUs due to architectural differences between Intel and AMD, and may also be related to the compiler optimizations. The performances differences can be shocking, actually.
Several MAME devs have recommended a middle of the line Core2Duo (around 2.5GHz) as a baseline for running stock MAME on a 64-bit Windows PC.
I don't know how your CPU compares to what they recommend, but keep in mind that traditional benchmarks won't normally show the kind of performance differences that you'd see running MAME.

Sorry to go off topic, but yea I have read that too. I'd be really shocked to find out SF2 and MK2 won't run at full speed with Groovymame on my CPU if done correctly. It's a black box to me though and anything could be the problem. All I know is that my XBOX ran SF2 and MK2 back in 2002 with no screen tearing problems etc. If a XBOX 733 MHz Intel Pentium III can handle all this, then my CPU should have a ton of raw horsepower.
