the only think I don't like about AMD in HTPCs is relatively high power consumption. The best compromise I found was intel's E3300 dual core celeron- rated at 65W TDP but tested at 19-20W idle and ~28W under load. You need a level of power to play Hulu HD and quicktime. If you're just playing bluray, then even a celeron 430 is enough.
the A2 240/245 I think has enough power but I think it's actual power consumption is double the E3300.
I have my E3300 coupled to a motherboard with onboard Nvidia 9300 graphics. It's good enough for hulu HD, 1080P quicktime, and bluray.
other than the power consumption though, that motherboard is very good for HTPC. If power is not a consideration, then the above setup would work great.
