Thanks to all for all the great input, I'm seeing that the choice of a 790x
( SB750 ) MB is the way to go!
But now the dilemma of the video card, I want to stay all AMD ( ATI is AMD )
for a pure approach.
I chose the "Radeon HD 4670" since it has the best HD video support ( no 3D
game support, but that is not what I care about for this system ).
But... for $25 more there is the "Radeon HD 4850" the 48xx is the latest and
greatest ATI series which can go head to head with GeForce 9800 GTX ( but
again not an issue with me )
Here is the rub:

8 you will see this:

If you are a Linux user but dual-boot into Windows to play many of your
games, by all means the Radeon HD 4850 is a great graphics card for you.
This graphics card -- which is the first to break the TeraFLOP barrier --
sells for less than $200 USD and it's been shown to deliver excellent
performance on Windows. On Linux though, the GeForce 9800GTX, which is now
similarly priced to this RV770 GPU, is the performance champion in all but
Enemy Territory: Quake Wars and the 2D testing. This should, however, change
with future Catalyst updates when this driver bottleneck is addressed.

If you care at all about open-source support for discrete graphics cards,
get the ATI Radeon HD 4850. The Radeon HD 4850 already works with the
xf86-video-ati driver and will be supported by xf86-video-radeonhd with due
time. Later this year we should hopefully see open-source 2D, 3D, and video
playback arrive for the RV770 graphics processor (along with NDA-free
programming documentation for this ASIC).

Thus should I invest in the 4850 since it's slated for OSS drivers (and
NDA-free access for dev's now that's cool ) or go with the GeForce 9800GTX
workhorse that's currently got the better drivers?

Seems phoronix labs it a reall good source for Linux HW testing insights:
