Both graphics chips are the same Nvidia Maxwell technology though and the Asus' one is quite a bit stronger.
MSI = GTX 960M
ASUS = GTX 970M
For gaming the Asus will be better.
Actually the MSI has the 970M, while the ASUS is using the 960M.
The ASUS is using the newer Intel HM170 Chipset / 6th gen CPU
MSI is using an older Intel HM87 chipset / 5th gen CPU
The ASUS comes available with different CPU options, an Intel Core i5 6300HQ processor or an Intel Core i7 6700HQ processor.
The ASUS is running the latest Windows 10, while the MSI is running Windows 8.1.
ASUS ROG GL752VW Specs
MSI GT72 2QD DOMINATOR Specs
Both look like decent laptops, but personally, I would chose the ASUS.
