Would this PC Spec be good for HD Video editing.?

Heres the spec:

Power Supply Standard 650W - Included

Processor AMD Phenom II X4 955 Black Edition, Quad Core (AM3, 3.20GHz, 8MB Cache)

Heatsink and CPU Fan Standard Heatsink and CPU Fan - Included

Motherboard Asus M4N68T-M LE V2, 2xDIMM, Max. 8GB, M-ATX - Included

Memory 8GB (4 x 2GB) Mushkin PC10600 1333MHz DDR3 (+£60.00)

PCI-E Graphics nVidia 9800GT 1GB (+£20.00)

Sound Card Integrated 5.1 Channel Audio - Included

Primary Hard Drive 1000GB SATA II - Included

Secondary Hard Drive Not Included

Operating System Genuine Windows 7 Home Premium (64bit Version) - Included



Would this be good to use for HD editing in Sony Vegas, Cinema4d, Adobe After effects etc.

I want it to edit very smoothly with no lag and render fast.|||It looks good enough but I have some suggestions to help it work better:



Step up to a 6 core AMD processor or an intel i5 quad core.



Try to find a GPU with CUDA. For similar price try the 1gb GT240.



Your video editing will go faster if you have 2 hard drives in RAID 0, or 3+ hard drives in RAID 5 (for better reliability).
