As it is only about £84 (-VAT) a month to pick up a dual G5, it looks like a relatively viable option - still it would be good if there was some sort of financial advantage/potential to the beast.
Who is using one with FCP 4? Is it much faster (at present I have a Dual 1 Gig), is it effectively Real Time editing? How much Ram should I slip in? (Will it fulfill all my wildest dreams, will it make me richer?

)
(Also will it make a big difference with DVD Studio Pro 2?)
