I'm looking to buy an i7 720QM or i7 620M.
I was looking at the benchmarks on the site:

And I was shocked.
If you take a look at the Cinabench Single-Threaded benchmark, the 2.66Ghz 620M gets about the same score as the 1.73Ghz 820QM.
I mean even in Multi-Threaded apps, 5.32Ghz should not be so far behind 6.92Ghz. But in Single-Thread?
WTF!
The reason I'm thinking of buying the 620M is because overclocking it to 3.06Ghz x 2 = 6.12Ghz, where as the i7 720QM for around the same price would gain me just around 7.02Ghz, and battery life would be abysmal.
I need the performance because I'm a photographer and I render together 20-80 Gigapixel images.
But at the same time, I'm going to be using the laptop for gaming while on the road, where 3.06Ghz will definitely defeat 1.8Ghz, since most games including Crysis and any emulator will only utilize the first two cores. So basically, you literally can't run a PS2 or DS emulator on the i7 720QM. So much for performance.
So is anyone willing to clear this up for me?
