I'm a bit late, but I was watching anime.
I needed the quad for stuff like supcom, which hogs the processor and slows the game down (even with my quad if I go over 3k units or so).
SLI is a sweet deal with the 8800gt, and I'll probably sell them and go for the 9800gx2 (was it? can't recall the exact name), probably funding the new card completely.
As for MCT, our schedule changes every 2 months, I've had introduction (general stuff), hardware/networking (~12 hours technical a week, 6 weeks) and now it's webdesign. I'd say that's a decent start to at least know a bit about computers (and I took informatics the last 2 years of high school, which was 10-12 hrs/week).
