Ok, heres one for you. I have the MSI brand 5900U on my system. I also have the MSI Live Monitor loaded, which works like the Windows Update....checks your system and lets you know when there are any new updates. I just ran the MSI Monitor and saw that MSI has the MSI version 52.16 but they also have the Nvidia 52.70 version update. I loaded up the 52.70 version and sure enough thats what it is. I can't find anything about the 52.70 version on the main MSI site, only through the MSI live update. Maybe Nvidia is giving it out to the manufactures first? Anyway it looks great on a short test of BF1942.
