Just got a HPzd8290 notebook with the intention of running Sony Vegas Software (or similar/better?

). But have just got cold feet and I'm wondering if the spec is up to it. If not I can still return it. It's a great looking notebook 17inch WXGA HD screen - Intel Pent.4 Pro.650 w/HT 3.4GHz -100GB (4200rpm) HDrive - 1024 MB DDR 553MHz SDRAM Dual Channel - ATI Mobility Radeon X600 (256MB ded.) DVD dual layer. Is this a good set up or lacking in any departments - I would greatly appreciate any comments to warm these cold feet!!!
