Ok, today is the day it goes on sale. I know many here have already been using it. I just ordered the free upgrade for my recent Acer desktop purchase.
Would it be best to do a full install when I get it?

Everything you do takes its slice of the pie. Software code is imperfect, there are artificial limits etc. AFAIK the only way to tell what's too much RAM is when, after buying/installing it, everything's the same. ;-)
Best way to spec RAM that I'm aware of is to just read reports from those folks who do all sorts of hardware reviews -- they've seen how whichever version of Windows does on what hardware with 2, 4, 6, 8 & so on. Vista likes/needs more than XP, & while the base requirements are low, 7 really likes more. When Vista 32 was new, 2 GB was cool -- at least double that with 7 64. That gives you a baseline -- next check out your hardware. Running an AMD quad I hurt when it comes to RAM bandwidth. An I5 or I7 does better. You should be able to get a fair idea by reading reviews of hardware using the same CPU & chipset with various amounts of RAM & benches for encoding & P/Shop. That should give you an idea of bang-for-the-buck (or GB) for the way you'll use it most.
Here's another plus I've noticed using Win 7. Vista had some kind of throttling action that limited bandwidth on gigabit Ethernet connections. This tended to limit the utility of network RAID devices. However, I wish to report, that I am getting close to 95% network disk read and write speeds, as compared to local disk operations.
