Yes, that's it in the sig. This model to be exact.
It was down to this or the 17" version of what I posted for you. After configuring the MSI it came out to about $350 more than this for very similar specs, except for the graphics.
The 560m in this plays Skyrim at almost all high or ultra with fps in the 30ish range, lower settings to mixed high and medium and I get a very playable 40-50 fps give or take, and it still look great. The 570m in the MSI is probably 15-20% faster, so that should give you a good idea what to expect.
Keep in mind that's with the 2670QM pushing it, nice powerful but cost effective cpu.
This laptop also required full updates on bio and drivers to fix known keypad issues, but overall I'm very happy with it today.
It was a tough decision, but I don't think I would have gone wrong either way. Both very powerful laptops with good warranties and they both look great.
