Not that it wouldn't work, but keep in mind that the speed of this product is the 250MB/s, which is PCIe x1. Most video cards require PCIe x16, at least that's what the specs say. I've seen tests of x16 cards using fewer lanes out there.
Er... Take it you didn't read it's notes?
Oh I know. It's a x1 lane PCIe slot effectively. It would work, but wouldn't be as fast as being in x16 lane PCIe slot of course.
But it would give you a good way to 'test' your macbook to verify the graphics are dead. I bet if you went into the system profiler with one of the systems with a dead 8600, it wouldn't even show the onboard graphics at all.
Bhoy, you guys are really hopefuls!!
Sooooo.. Anyway...
how many MacBookPro's are 2.33Ghz with 8600M GT?
