Well, there is no reason to buy a slower GPU just because CPU is better. GPU is everything in video playback, the main task of HTPC.
- Decoding is done by a decoder in GPU: UVD (AMD) / MFX (Intel)
- Deinterlacing is done by stream processors in GPU (AMD) / Media Sampler+EUs (Intel)
- Post processing is done by stream processors in GPU (AMD) / Media Pixel Ops+EUs (Intel)
- madVR (if you are interested) uses stream processors (AMD) / EUs (Intel) exclusively via Diret3D API for its complex algorithms.
So CPU plays very little role in video playback.
SVP (Smooth Video Project) is an exception, that requires both CPU and GPU power (via OpenCL). A10 is just excellent in this case (good balance between CPU and GPU, and good CPU-GPU communication via improved memory controller). None of Intel can touch Trinity.
BTW a typical CPU-intensive task related to HTPC is video encoding. In x264 encoding, A10-5800K is roughly 20% faster than Core i3.
