LR4 CPU query
Since upgrading to LR4, I'm seriously considering going to an i7 3930K with 6 cores. Plus - unlike the QX9650 - it has hyperthreading. I'm hoping that the introduction of the new Ivy Bridge CPUs will cause the 3930K to drop more in price.
Hyperthreading did not show value in PS CS5, comparing the i2500 and i2600. It also seemed to gain little beyond 4 cores.
