Gaming performance
We can benchmark the board with both the discrete GeForce GTX 680 and HD 4000 Graphics IGP running the same tests, albeit at different speeds. The MSI's IGP is clocked in the same as the Gigabyte's - we confirmed this with a detailed look - but functions a touch slower.The Batman test just takes in the discrete card; the performance is the same on both boards.
While the low-end Just Cause 2 focuses on playable framerates for the IGP. Again, the performance differences are minor.
