Hi all, short time lurker here, 30+ year PC (et al.) user. Finally pulled the plug on my boutique custom PC and ordered up an imac! After a few visits to the local apple store and a nice long chat with a helpful salesperson on the phone, I got the i5 2.7 with the 6770M/512MB GPU and that gorgeous 27" display. As far as I could tell from following as many GPU threads here as I could, it seems the upgrade is worth it for: gamers, lots of heavy video work, CAD/3D rendering. The limit of our gaming is my 2 and 4 year old playing Angry Birds, our video work is mainly confined to prettying up the kids' videos from school and putting them on Youtube for overseas relatives to watch, and as far as 3D goes, well, does Google Sketchup count? Because I think that's about it. Other than that, we do the usual picture/mp3 management, office docs, surfing, Netflix, etc. I'd also like to take advantage of the goodies in iLife. But nothing too intense. I'm confident we have plenty of computer for what we need, but I'd like to ask y'all, what else is the additional GPU juice good for? With the exception of resale and "future-proofing" are there other applications that we'd see a benefit from the upgrade? Sure it was only $300 to upgrade to the i7/6970M, but hey, $300 can get me Applecare, one-to-one, and a couple of flash drives. Looking forward to joining the ranks!
