The eurocom bios is msi but its not the original gt60 bios, yeah that bios is good enough for overclocking, i happen to live in a hot country and i don't wanna see my temps go up to about 88 so i flashed to a msi gt60 stock bios. Even on stock clocks it can handle almost every game you throw at it, i only overclock a bit if i want to game in 3d with tridef. Here is a link if you going to use Eurocom bios. Geforce 306.02 - Modded - Dox's Customised Geforce Releases - LaptopVideo2Go Forums The Eurocom msi bios is very weird, those drivers i modded and install had optimus issue, even the drivers from eurocom drivers is not working for me. What i do is install dox drivers first, then mod the latest driver to install. If you flash to stock msi bios you can install any drivers without modding. Installation is pretty easy, fill up the gap with thermal pads on your gtx670m heatsink, You will not need to use the x bracket. As long as you get idling temps 38-40 your good to go ( I live in singapore and its very hot here) Good luck.
