RunLuke :
what glitches? What is your budget, that's pretty important.
For video pretty much everything, depends on how fast you want to be able to render and scrub your timelime.
What editing software do you plan to use? That's important too.
A good GPU works wonders in premiere pro. You need an ssd for your media cache, that makes it a lot more smooth to work with.
I've edited plenty of 1080p video on an ancient Macbook pro 2.66GHz i7, 8Gb ram without noteworthy issues.
But I don't know jack about laptops and my opinion is that they are a waste of money for anything regarding heavy media production, a desktop is cheaper and better for it. Also allowing you to upgrade along the line.
Thanks RunLuke I am wanting a desktop and I am using the GoPro suite and Premiere. As for the Glitches they are hanging up slow or stop go video, missing part of the video. My machine is old and I need a new one. I am a Windows girl though and can't change. Budget around 900 or up. I just don't know that much about graphics cards and was looking at this machine (Dell XPS X8700-2812BLK Desktop) and wondering if it would work?
