I'm looking to build a new PC to solely run Photoshop CS4 and want to know which is the best processor to use. Is the i7 better than the Core2 Quads or are they both overkill - could an i5 with fast scratch disks and plenty of RAM do just as well?
The comparison is between an i7-750 and an i7-860. We know that the i7-860 is faster and more expensive. What would be required is the same benchmark of an i7-860 with and without Hyperthreading. Don't get me wrong; I'd also go with the i7-860, but not only because the Photoshop benchmark results are slightly better.
