Hi, I'm studying web design in college and it's time to upgrade from my PPC white imac. After much research, I've decided a 27" i5 or i7 refurb would fit my needs the best but I'm still a little unsure of which refurb to get: the 2009 i7 at $1699, the 2010 i5 at $1699 or the 2010 i7 at $1899? I'll be using CS5 extensively for graphic design/photography (I'll probably be running photoshop, flash, in design and dreamweaver everyday, throughout the day, at the same time, etc.), very light video editing (mostly vacation videos for web use; nothing professional) and occasional gaming (The Sims and casual games; nothing too taxing on system resources). The big question is which feature is more important for my situation: the hyperthreading capability of the i7 or the video card (4850 vs. 5750)? If hyperthreading is the most important feature, is the better graphics card and ghz in the 2010 i7 worth the extra $200 or will the 2009 i7 suffice? If the video card is more important, will the 2010 i5 suffice or should I go for the 2010 i7 for hyperthreading and more ghz? Obviously, if they're of equal importance, I'll be shelling out $1899 for the 2010 i7. I'd like to save the $200 if at all possible because I have to pay tax and get Applecare (eventually). Ideally, I want to choose between both $1699 models but if I must, I will pay for the $1899 model. Thank you!
