i've got a 2.2 MBP C2D, the santa rosa variety purchased late 2007. the logic board has since crapped out on me (that's another story). anyhow, i need to replace the logic board but i was wondering is there any possiblity of replacing it with another specification? say... a logic board before the unibody's or any major changes were done to the MBP, like maybe mid/late 2008 varieties. it would be great to be able to get a boost in CPU power and a better GPU (i have the basic model so that's the 256mb geforce which isn't bad but could be better). i know what i am doing DIY wise so i'm just wondering if i can order updated parts and if it would be compatible. thanks.
