The GeForce 8600 GT is largely under Radeon 4670HD of today, 3X slower than Radeon 4850HD that juice the quad-core iMac. In fact it’s marginally faster than GeForce 9400M of Mac Mini and white MacBook, more processing power, but same memory bandwidth!

So why Apple is selling this old videocard dubbed as GT120 on MacPro? It has no sense!

Yesterday night I just finished Lightroom 2 transition, iTunes migration, I put music and photos on their own partition to have a small boot partition at the beginning of the 500GB hard-drive. I modified LightRoom 2’s infos to launch in 64-bits mode instead default 32-bit. And finally calibrate the screen using Spyder 2 Express. Better rendering.

One dawback with the gorgeous screen on the 17″ is that background pictures doesn’t cope with it’s 1920×1200 resolutions and every jagged part or compression block is too visible, so do your background image by yourself
