yes you can. its just like a motherboard with built in graphics. there will be a bios option for which to perfer. but generally just plugging in a card will make the system want to use it over the apu. but each board is different and you might need to just RTFM.

Thanks, but will it still be a quad core? My friends tell me one of the cores will be disabled and it'll be a tri-core if I use a non-dual graphics card. (6670, etc.)
And I was having doubts about it.

I'd love to, but crossfiring would increase the power usage and it's not a good idea since I'm not the one paying the electric bills.

Crossfiring with an APU would so little difference in energy usage it wouldn't even be worth noting. That said, you cannot cfx a 7770 with an APU so it is a moot point.

Enabling the on board gpu will not disable one of the CPU cores. The chip is designed to allow them all to work.

Toms has done a few articles about crossfire or hybrid crossfire and they found that many times mixing a PCI-e gpu with the onchip GPU will actually lower games FPS. In crossfire the faster card has to slow down to match the speed of the slower card. So in this case you would have 2 slower gpus, instead of 1 faster card.
I would run the HD7700 without crossfire.
