Hey guys im a new college student and am looking to take advantage of the student discount for a new iMac. I already have a macbook pro but I do alot of photoshop and editing overall in which im interested in buying a iMac. I was wondering with anyone who has one of the new iMac's that if they play HD videos very well no matter what codec (.h264, mkv) it may be. I do understand that the 9400m is a integrated graphics processor which uses the processor and ram, I will not play games at all just play hidef videos as well as edit. I would like to make sure with someone who has one that there is no lag of any sort or any problems with hidef videos. Cliffnotes: - New iMac 24", does it play hidef videos well, wont be playing any games just dont want any lag if I were to play hidef movies like it is on my macbook pro. would me building a pc be a bit more worth it? I would like to stick with a mac but if the iMac is sufficient with playing hd videos and myself being able to edit them would be great as well.
