Okay, I've settled on these two refurbs: 2.8GHz Intel Quad-Core i5/4GB memory/1TB hard drive/ATI Radeon HD 5750 graphics with 1GB memory 2.66GHz Intel Quad-Core i5/4GB memory/1TB hard drive/ATI Radeon HD 4850 graphics with 512MB memory The difference between the two is only about $170, which isnt a huge deal. Updated processor and graphics card, but would it be a hugely noticeable difference? Ill be using it for standard things (internet, video, etc) but Ill also be using it for music recording/editing (which is why I figure on the quad-core). I won't be gaming or doing video editing. I just want to ensure that i'm getting more bang for my buck. If I really won't even notice the difference, then I'll stick with the 2.66GHz. What do you guys think?
