You are badly in need of a GPU upgrade to play this game correctly.  With very low screen resolutions, and all low quality settings, you may get it to more or less work, but is that what you want from a game? 

Now, I don't even KNOW that your crashes are caused by the loq quality GPU, although the red flag is waving vigorously over it. 

This is the only game that crashes like this though...It doesn't crash when customizing characters in the main menu or single player Garden Ops, but it crashes on multiplayer Garden Ops, and any other game mode with online multiplayer, which makes me think it's not the graphics card...However, if it is my graphics card being weaker than the minimum specs I'll buy the GT 8800 graphics card, but I want to see if there's anything else maybe I can do.

The GT 8800 was really something special, back about five years ago.  New ones would be hard to come by now, although I think that a more easily found GT 640 would be close to matching it, and a GTX 650 would beat it by a good margin.

I found a GTX 650 at amazon for $98.88 I'll probably get that when I get a chance...How much of a difference is GTX 650 and GT 620 (the one I have now)?

And will it fix the crashes that I've been having? Because I don't want to get the graphics card and then it still crash...

Long distance diagnostics is very difficult to do.  This is a peer to peer gamers' website, and we don't have anything like the kind of resources that official tech support people have.  I have the feeling you have some problem other than the weak GT 620, or your complaint would be about graphics, not crashing, however, we tend to point to those things because there is no support when you have that poor of a video component, anyway. 

If you did have a decent setup (and you will almost certainly also need an upgrade to your power supply), Help Center's Official Support techs just might pinpoint the fault quickly enough.  It sort of depends on who you've connected to.  The quality of personnel is variable. 

Jumping back to the original message/error.

Faulting module path: C:\Windows\system32\nvwgf2umx.dll

That's the nVidia Drivers.  Uninstall, Restart, Reinstall latest.

If that doesn't cut it.  Uninstall, restart into safe mode, Run Display Driver Uninstall (or DriverSweeper but it's not prefered), restart.

Another guy recently was having errors that appeared to be nVidia Driver related and it turned out to be bad sectors on his Hard Drive that he fixed with SFC /Scannow

I would bet yours is corrupted drivers though.

Here's some copy-pasta that explains it better.

Try this. If you aren't used to Safe Mode or scared of BSOD don't do it.

Uninstall your nVidia Drivers from Control Panel (all)
Restart into Safe Mode
Run DriverSweeper
Restart
Install Latest Drivers

If you have a BSOD on restart. Go back to Safe Mode. Go to System->Device Manager->Display Adapters Remove them, restart.

Safe Mode /w Networking will save the day

--- This is another popular tool, it's an alternative to DriverSweeper

I did the SFC /Scannow, didn't show any errors, completely uninstalled the drivers and reinstalled the latest version, tested by customizing characters, worked, went to Team Vanquish crashed with a new error:
