So i was thinking, is it possible to retrofit the 8600m GT into my CD MBP? Sorry if it sounds stupid 
Then again most MXM solutions are on 17" or larger laptops and you can only get a new card from the original laptop manufacturer.Some new laptops put the video card on MXM modules that makes them upgradable -- the 24" iMac does this too, though I think it's mostly to make it much cheaper for Apple to offer different cards as a build option.
Sadly, the MBP does not use this... so, there may be hope for this in the future, but not with your current hardware.

Great concept though.

yeah that slipped my mind. The gpu is soldered on or something right... i bought my mbp wif the thoughts of decent gaming in mind. I mean, i had thought the X1600(256mb) was quite a contender for gaming but i was darn wrong. NFS:MW @ that time was barely playable and i was anticipating @ least a smooth framerate @ native resolution in full detail.. now that they have an Nvidia gpu inside that has a 60% increase in performance... really makes me feel kindda sore.
Let's not do this again.Yeah, unfortunately the x1600 was a low end card even last year when it launched. (Despite what some people on here will try to tell you.)

I haven't seen any laptops that use MXM either. I do occasionally see a card pop up on eBay though.
The x1600 Is actually a Mid-Range Chip.
No, it wasn't. It's performance was roughly similar to Nvidia's old mid-range part from years past, and was nowhere near what Nvidia was offering in that price range when the x1600 launched. ATi just tried to get away with selling it for high prices. Still makes me mad when I see x1600s in stores going for crazy > $100 price points.
I mean a company can call it whatever they want, but if it's actual performance can't match up with parts in the mid-range price point, it ain't mid range.
For around $80 right now...
X1650XT ~ 7600GS
Just pulling numbers off of NewEgg.x1650XT For 80? That is as good as a 7600GT (Took 3 refreshes to do it though but ati had a card as good for the price.
