The best thing with an Apple Update is that you can start looking forward to the next one. I predict a new iMac update in March 2010 where we will see some juicy ATI 5XXX mobility GPUs![]()
I hope for you that this is how it going to be (I think it is) I myself have chosen to buy a cheap gamer pc, and an iMac and use the iMac as a screen when gaming.
Best of both worlds, and it's cheaper than buying a Mac Pro
