I'm seriously considering the purchase of an iMac 2.4GHz Intel Core 2 Duo, and I currently own an iMac 1.8GHz G5, which I'll be selling. I've been looking for a good web site with benchmarks to compare the two. Any suggestions? In general, how do the Intels compare to the PPCs? Am I going to see a big performance difference? I appreciate any input you can offer. Thanks!
