Is single core Atom enough to emu PPC?

I'm thinking of builing dedicated micro PC for WinUAE in A600 case. I found this Intel Nuc board with E3815, 8GB ram and Intel HD Graphics @400Mhz.
But I wonder if that enough for 060 and PPC emulation?
Or do I need dual core Celeron or maybe i3 board?
many thanks

A strong dualcore is recommended for emulate an 060+PPC.

Dual core is required. Speed is recommended. The faster the better.

Thanks guys. Gonna save up for good i3/i5 mini board.

Edit. Trouble is i3/i5 boards are expensive and needs more space and power.
I found that integrated Quad Core celeron board, I wonder how this will perform?

There are plenty of bay trail quad core atoms with "win 8.1 with bing" around for roughly $100 (guleek i8, pipo x7,...). Clocks range from 1.33 to 2.16 GHz. Far enough for 68k/os3x emu but not sure it would be fast enough for ppc... I should try on my guleek i8 vs my dell (core i7)...

Careful - in my experience, for whatever reason (even though I _think_ it's only doing map-the-screen-onto-a-plane with optional FX streams), 3D performance is surprisingly a major factor. My Pentium N3530 is enough to plow through the vast majority of MAME titles using Direct3D as a draw surface, but seems to be inadequate to even keep Workbench going at 60fps without major sound lag (for which I have very little rational explanation). DirectDraw works better, but not perfect, and (for instance) the end of the Odyssey demo (basic A500 configuration, run from floppy) with scrolling credits falls behind on simply drawing frames, regardless of how high I set frameskip.

I verified that the correct Direct3D, et al downloaded and installed (running Windows 8.1 64-bit), and the logs look clean, it's just pitifully slow, unlike any other emulator I've tried (it's a Dell Inspiron 11 3000 - very nice GP laptop/tablet otherwise!).

tl;dr there may be more to adequate basic WinUAE performance (completely ignoring PPC, etc.) than just the processor.
