Thanks Guys for all your input
the DVD editing is mor eof instruction based DVDs rather than high end productions with loads of animations etc. We will be editing in HD though. DVD edititing will not be a full time thing, probably 1 or 2 dvds a month.
I think i have opted for a AMD 4600 X2 (9.2GHz Eq) Dual core CPU, 2GB DDR 667, 500 GB SATA Drive etc
I compared the benchmarks for this processor compared to a dual core and the difference in speed processing speed comapred to price isnt really justifiable at this stage.
What do you guys think?
