I was originally going to get a Mac Mini, but since seeing the refresh and the faster SSD, I'm kind of tempted by the 27" iMac. I've decided if I do get an iMac that I will be getting a 512GB SSD and will upgrade the RAM to 32GB aftermarket. I also do some video encoding via Handbrake so I decided I would go with the i7 to take advantage of the hyperthreading. I was wondering, however, if I could get away with the GTX 775M 2GB, since I don't game at all, and I don't edit video or photographs. However, I AM thinking of running my iMac with a 1280x720 HiDPI resolution because I like to sit almost four feet away from my monitor and I have bad eyesight. It'd be nice to have everything be absolutely huge so I can read it, like in these screenshots: http://forums.macrumors.com/attachment.php?attachmentid=346227&d=1341231609 http://forums.macrumors.com/attachment.php?attachmentid=346221&d=1341227958 But I've read that HiDPI mode is more intensive on the GPU than regular resolutions. I don't currently understand WHY, but with that in mind, do you think the 775M would have enough power to run HiDPI mode for at least the next four years without stuttering at all with OS X animations? I will NOT be doing any gaming whatsoever, I just want to make sure I have the option to blow everything up without having all the OS X animations stuttering a few years down the road. If I would need the 780M to do that, so be it, but if it's not necessary I think that money would be better spent towards getting a good UPS for the computer.
