Hi,
If you're considering a MSI GE70, I've configured one for you (http

/www.ibuypower.com/Store/MSI-GE70-Apache-Gaming-Laptop/W/225566) - $1,309 with free shipping, but I added a coupon code (Promotional Code - BOXBOX5) for 5% off purchases over $1,299 so the final total comes out to $1,243.55.
The technical specs come out to an i7 4710HQ mobile processor with a 860M GTX 2GB, which should run Pay Day 2 at around 60-70FPS, high settings.
As for DayZ, It should run on high settings, but I'm not completely sure on the FPS.
This custom configuration includes a free MSI gaming mousepad and Sistorm mouse (courtesy of MSI).
Check out our other configurations and let me know if you have any questions!
