For video editing, if you are doing it on any sort of professional level you might want to get more ram.
Also, I'd advise a larger hard drive, and perhaps a SSD down the road.
If you have any money left over put it into your PSU, you can always use it down the road.
i wud have got a 1tb but cause of the hard drive crisis why waste money on it. I dont do professional lvl movie editing, I just use sony vegas 11 and render videos in 720p. with the ssd and psu that nots rlly important right know but i keep in mind about tat in the future. thxs 4 the advice
