Ok, what im doing is upgrading my MSI GT 70 laptop GPU with a GTX 780m. I have been wanting this for awhile and I have found some in recent times with good pricing on ebay. Now my question is because I have had trouble finding information on the subject, will a card from an Alienware work like a standard Mobile GPU? Meaning can I just stick it in any compatible MXM 3.0 Port and it will work. For the record, I am coming off of a GTX 675m. The problem I have heard in the past is that Alienware/Dell use custom Bios which lock down certain features. I am curious here if I buy a GTX 780m from an alienware if it will work fine in my MSI (MSI is pretty easy to do from what ive seen). Anyone have any information towards this endeavor I would really appreciate it. I have been searching the web but I have not found much on the subject (I can find plenty about upgrading GPU's, but nothing specifically pertaining to putting Alienware/Dell GPU's in other brand machines).
