Media Performance is important to analyse as this will be a primary feature of the card so we started by analysing HQV results. We used a few other cards as comparisons with the HQV benchmark.
This HQV Benchmark from Silicon Optix are great tests of the playback quality of HD DVD, DVD and Blu-Ray movies. We used Catalyst 9.5 and Forceware 197.77 for our testing. It is worth pointing out that these tests are in some ways very subjective and are tied into not only the hardware, but the drivers. We have noticed some improvements lately with the recent Catalysts and the HD5770 was included for the sake of being thorough.

The Asus Bravo gives a very strong result of 106 and although we have seen some recent improvements in the Forceware drivers we still notice a few issues with antialiasing and random artifacting with noise suppression algorithms. To be fair this noise can be adjusted which therefore affects the overall level of detail throughout.
All things considered the IQ results are high which is verified by real world use. I would be very happy using this card in a low powered media PC full time.
We then played back the Bluray disc of AVATAR to judge CPU load.
nVidia's DX 10.1 compatible graphics cards can offload the CPU when decoding VC-1 and the PureVideo engine is considerably better than previous generations. The average CPU load is around 10percent but we noticed a peak of around 24percent in a few locations. As a reference point we played around with a Geforce 210 model and we noticed around a 10-15 percent increase with these figures.
