Conclusion: The NVIDIA GeForce 8300 chipset has shown some potential to become one of the best integrated GPUs for HTPC use. Despite its aim towards budget gamers and/or HTPC users, it is not skimping on the features.
Summary: After extensive testing, we can conclude that the Asus M3N78 Pro and its Geforce 8300 chipset is a success. Compared directly to Gigabyte's GA-MA78GM-S2H and its AMD 780G chipset, the nVidia chipset board has the power efficiency edge in all areas, saving up to 11W depending on the load.
Pros: Excellent, efficient high definition playback, Low power consumption, HybridPower reduces power draw modestly, Overclocks well, Good fan control, Express Gate convenient for simple tasks
Cons: 3D performance lacking, HybridPower savings much less than expected
