I've done some reading before posting but I'm still a bit confused... I even check on iFixit to see if the question was asked, but no luck...or I overlooked... I pre-ordered the new iMac 27' last november/december. 3.2Ghz i5 with standard 1TB HD. Upgraded the Graph for the 2Gb 680. 1. Can I swap an SSD in it or is it too late? 2. Can I upgrade the graph card with the new ones released a few days ago? (708 with 4GB)? Thank you!
