I'm building a new PC this month, and I've noticed that right now I can get an i5 750 @ 2.66GHz or an i5 650 @ 3.2GHz for the same price. I understand that the 750 is a true quad-core while the 650 is a dual-core w/ hyperthreading, and going true quad is generally a better idea. But is the extra speed of the 650 going to make up for that? I do a lot of work in After Effects, so multiprocessing matters to me. I'm just not sure which of the two will give me a better raw speed across all the cores, fake or not.
