Looks like Nvidia got it right finally, Purevideo VC-1 and H.264 hardware decode acceleration outperforms UVD and even lower cpu usage in MPEG2 vs HD3450 as well as higher gaming fps in real games.
In H.264 and VC-1 decoding process the card keeps CPU utilization keeps within 5%, better than HD 2400 pro and HD 3450.
G98 only have 8SP, but a higher clock. In the test the performance is better than expected. In other words the card have a good HD video playback ability and standard 3D performance.
