GT70 0nc GTX 670MX Driver Crashes, and BAD performance.

Question

I purchased a gt70 ONC 494US and at first I updated all drivers and software on win 8 x64, I tried running multiple games off of steam and none of them were running smoothly, some of them not at all, (borderlands 2, arma II, fallout 3.....) I installed an SSD and a fresh version of win 7 64 ultimate, used only drivers from MSI, and still had crashes and couldn't even run a benchmark.
The only solution I have found to run a select few games, is by uninstalling ALL nvidia software and drivers, using windows default VGA drivers for the 670mx, however, this only works for a few games, and some others won't start because they don't find a capable GPU.
I have read MANY forums, most of them go through the typical, use the nvidia control panel to change the power settings, global settings, and roll back drivers to the originals. NONE of this made any difference.
I have read that there is a firmware beta ec flash? But, even the tech forum from MSI the link didn't go anywhere. I know this is a common problem, and especially with steam games. Yes, the power light turns orange, and i turn on turbo mode, I also turned on the indicator showing the nvidia gpu is being used, but games will not get past the title screen if they start at all, and the nvidia driver crashes.
Help?

Currently I am trying the new 340.52, before this I had reset to FACTORY image with the original OEM drivers, 306.14 (I believe). For the intel, again I started with the OEM hd 4000 drivers, currently I have the may 2014 drivers, 10.18.10.3621. Before hand, no there was no error, just a frozen game I had to kill with task manager, now I am getting the error that the vram is full. Using GPU-z I see that the dedicated vram isn't even being used. Ideas?
For the BIOS, EC firmware update, you can find them under the download page of MSI.

For the game settings GeForce Experience provides, I wouldn't say it's an optimized setting but the settings only for your references.
Since the tested game environment and system configurations might be different, I'd go for my own settings in order to find the best gaming experience.
Like BlueAlexFPS said, the GTX670M has similar performance as GTX765M, it would be ridiculous to have the same performance like GTX780M. If what you said is true, then why they are they putting 780M out on the market?
I'd keep the graphics driver from MSI website, since a windows generic driver could gives you only the basic level graphics performance and not to mention without the Optimus, you wouldn't know if which graphics it's running.
*Make sure you're having battery and AC adapter both plugged while running the games.
