My max upgraded to 2.8 i7, HD4850 (512) graphics card iMac from Late 2009 is back in the Apple store getting the graphics card replaced for the 3rd time. Since it's almost 5 years old now, I was hoping to replace it with a new iMac. I thought I was going to get lucky when the rumors were that they would be updating the iMac line any day now. They were right. Sort of. Today's low-end iMac doesn't help me. I don't know what to get now. The 27" screen was a little on the big side for my desk, so I wouldn't mind dropping down to the 21" but I don't know how I should spend my money in the wisest way. I thing I overestimated my needs on this last iMac. Sure it was a beautiful screen, but my gaming is - I think on the modest side. Mostly just Blizzard games, Diablo 3, Hearthstone, and just recently the Mac Beta of Marvel Heroes. However, those games seem do be going a job on that HD4850 since it's being replaced for the 3rd time. Do I go with the 21" with the 1gb graphics card and the 256 SSD and get more ram up to 16gb and maybe get windows 8 and Bootcamp for games? Or go with the 27" again ang the 2gb card and SSD? I can wait a little while, but not that long. These graphics cards seem to only last 6 - 9 months. I'm hoping they update the rest of the iMac line soon. How much of a difference is there between the old i7 nehalem chips and the current i5 chips? I just hate the thoughts of spending $2,000+ again. I wish they would make a Mac (Pro) Mini. Some consumer friendly upgrade able Mac. Any thoughts?
