[QUOTE="globaldonkey, post: 699884, member: 49844"] I'm going through the same process and questions at the moment too. I can't provide any input on the dual displays questions, but can offer the following. Definitely I think the onboard graphics with the 890G would be a problem, particularly if you are looking at doing True HD / DTS HD (ie Blue Ray audio) over HDMI. It is not supported on any HD 4xxx, and is probably the main reason why you want to go HD 5xxx or Intel iGPU. I found a good article on the HD 5450 vs 5570 for HTPC. 1080i deinterlacing is the benchmark I usually uses as far as performance is concerned (mainly because all my home movies from my sony camcorder are 1080i), and it looks like the 5450 would be found a little wanting if you needed both 1080i vector adaptive deinterlacing and any other post processing. So the 5570 is definitely the way to go for option 2.
