I really dont know what to get here. I'm doing this build as a home/office work computer and I've been going back and forth between the I3 and I5 2500. The I3 is dual core with hyper threading while the I5 has four actual cores but no hyperthreading. I guess what I'm afraid of is the I3 will underperform because the dual core will bottleneck. But how much better will the I5 be with four actual cores but no hyperthreading?
