No offence, but I always find these kind of posts a bit pointless.
For a start you've not told us what you'll be doing.
For example, an 'ancient' 800MHz proccessor and a 32MB GFX card will quite happily run Final cut pro, and output to DV or export files for web/3g/dvd etc.
HD will obviously need a bit more oomph, but a 128MB Gfx and a 2GHz Dual Core will be fine for most HD editting.
These kind of posts I always feel are a bit ego driven, (I'm not saying I'm jelous of anything your quoting here, as I don't even know what half the model numbers mean), they just always seems to be a 'look what I've got/I'm getting' vibe, which I find very borring. Would you like me to list all the specs on all the computers and cameras I have, or will be buying? Nope, that's because no-one cares.
At the end of the day it's not what you've got, it's how you use it. I've seen so many vids from people with 10K+ rigs, that are really carp, compared to some vids I've seen from people using 'old' technology that cost a few quid. Again, I'm not saying you're vids are rubbish, but you don't need top end equipment to make a good vid.
