Well, let's see.. Where should I start?

- I have 16GB of RAM
- Brand New HDD
- Magic Mouse Works
- Magic TrackPad Works
- Logitech Mouse works just fine when plugged in through USB
- Should I continue on?

Way to go with the attitude when I and others are trying to help you.
 
I find that my logitech and bluetooth controllers start stuttering under heavy load as well (13" 2011 MBP). I believe it's a driver issue with OSX. My Logitech Performance MX works with every other computer I've tested it on. This even includes a lowly netbook w/ Atom processor under heavy load.

Not a RAM or HDD problem. Any suggestions guys?

I would say it's definitely a software/driver issue, but other users also noted seeing similar problems with Snow Leopard.
 
Plugging the receiver into the front of my USB hub works. Not stutters or jitters. Call it temporary fix, but it works and I'm satisfied.. for now.
