Hello everyone, I am having trouble deciding between these two CPU's, both of them overall come to the same price with the different options I have selected BUT I do not really want to wait another 3-4 weeks to order it because the quad cores do not ship until november, so the question is will I really see a difference between these two CPU's? Both the iMacs I plan on buying will have the 4850 and 8GB of RAM. Which one will I likely get the best game performance from? Should I just wait for the i7 instead of rushing forward? So what do you guys think?
