I'm excited about what Sandy Bridge has to offer me (mostly because I do not play a lot of PC games) but I'm a little worried about their role in the iMac due to their inherent ability to perform GPU tasks. I doubt they will have comparable performance to the current CPU/GPU platform when it comes to games and I wouldn't be surprised if Apple decides to make it entirely integrated and leave the GPU out of the next iMac configurations. Think about it. Most people who use Macs do not game (or hardly game) and it's definitely an advantage to leave the GPU out to save money. Those who still game will be able to continue playing games that are for the most part 2 years old (or older!!!) with no problems. I know that GPUs can increase performance in software other than games but the majority of GPU utilization is with gaming software. Has Apple weighed in on any of this? Could they still put a separate GPU in with SB? I am highly ignorant in regards to a lot of hardware tech so I may be completely wrong here.
