I'm looking to build a new system and I'm stuck between these CPUs. I won't be doing any gaming but will be running a lot of virtual machines probably at high performance, listening to music/recording, watching videos and general use plus Photoshop etc. The AMD is much cheaper (maybe for as reason) and does get lower bench marks. The two i7s appear to get similar benchmarks, I'm not sure if there's much in it? There is also the i7 3930 but thats about double the price! Would I notice much difference between these and what would you suggest? I'm guessing most would go with one of the i7s?
