@ TANKkiller47, are you running your M15x with GTX675m on it? I also bought a gtx675m (haven't received it yet) but I saw some posts today, stating that it would not run on a M15x. Are there any driver modifications that should be done? Or something extra that takes in order to make it work? Also my gtx260 bracket would fit or i will have to buy a more specific one?
