I am a digital photographer, I am trying to decide between the AMD Phenom II x4 945 vs the Intel I7 920 processors. Seems to be a $200.00 price difference, not sure if it is worth the extra? These are both from Dell.
If all your doing is editing photos professional grade, the i7 860 should be an overall cheaper choice than the 920. Performance would be equal or even a touch better. I'd also get the i5 750 before the AMD for your usage and they would be close to the same price.
