ASUS G75VX or N76VZ: Which is better for me?

First of all, i'm terribly sorry if I put this on the wrong section. I wasn't exactly sure on it, I thought this was the better place to put it. If it's on the wrong place, i'm sorry

Anyway, i'm an aspiring internet reviewer and I was looking for a powerfull performance computer to handle professional video editing software and full HD recordings/footage. I currently own the ASUS N53Jq, with a i7 740QM, GT 425M and 6GB RAM. I'm verry happy with it, best laptop i've ever owned actually, but I need a more powerfull one for the reasons i've already stated. I guess it would be also great if it could run games smoothly, but not a top priority for me. Most games I play on the PC is older stuff and the new stuff isn't very demanding in terms of specs (Dark Souls, Football Manager, Kingdoms of Amalur), nothing like BF3 or COD demanding since I hate these games xD

So I was pondering these two: G75VX-T4059H and N76VZ-V4G-T1196H (the sites' in portuguese, but scroll a bit down and you'll find the specs). I've heard great things from both, but I'm more leaned to N76VZ for it's higher HD space, better GPU (i'm assuming...) and significantly lower price tag. But i've heard the G75VX is the best performance laptop out there...

So yeah, that's pretty much it. Which one you guys think is better for my needs? If any of you has/had one of these laptops, it'd be great if you could tell me how good they are :)

Thank you for your time.

If you can afford it I MYSELF would go with the G75. They both are good machines but the GPU is much better in the G75. This is only my opinion of course.
