Okay...I do not mean to sound stupid, but I really do not know much about macs in general. I am a windows person and have been waiting for the new imacs to come out in the hopes of becoming a first time mac owner. I have been keeping up on the postings here and have of course run across many opinions which is great. Unfortunately it's been confusing! I use my computer for mid range gaming, office applications and media. From what I can see the upgrades from old imac to new imac yield a graphics card that you can not upgrade (must be intergrated into the motherboard somehow) and a lack of the obvious no quad core, etc. I can get a killer pc for less with more but of course apple products are known for reliability and lets face it the imac comes with a nice screen although the graphics card may not support it. Can someone tell me am I better off with the low end imac or build my own pc taking in consideration speed, ability to upgrade and versatility? Please guys... talk slowly and go easy on me!
