which would be better in games

Definitely the 965BE with the HD7770, here: http://www.pureoverclock.com/Review-detail/amd-trinity-a10-5800k-review/14/
You have quite a wonderful parts combination on both of those systems, good job erskipper!
Phenom II + 7770 will be better for games. You won't have to deal with micro stuttering or crossfire driver issues.
A10+6670 is for those with REALLY tight budgets. For example, if you want a quad core but can't afford a graphics card to go with it, you can buy an A10. Then later on, if you want more graphics, but still can't afford to spend much, the 6670 crossfire option is there. However, if you can afford a Phenom II and 7770 at the time of building your computer, then get that.
Also, get 2 sticks of 4 GB RAM instead of that 1 stick of 8 GB RAM. You won't be able to take advantage of dual channel with only 1 stick.
