I'm about to build a similar budget HTPC to digital foundry's under 300 experiment, and I wondered if the new AMD chip could be a better bet, using the IGP.
It will actually mainly be used as an emulator PC to play my PS2 collection and various other consoles.
It seems the A10 beats the G860 in everything apart from single threaded stuff. And the IGP of the A10 seems to be pretty much on par with the Radeon 6770, especially with 2ghz system ram.
I'm thinking most emulators like PCSX2 and Dolphin are CPU bound and single threaded, so the G860 might hold a slight advantage. It probably won't matter though, as the A10 should still run them at 60fps comfortably.
So it's possible the A10 is an even better deal for a budget HTPC gaming PC. At only 90 pounds, it's even cheaper, uses slightly less power, and should be quieter too right, without the additional GPU fan?
