no either its crossfireX or Sli irrespective of what cpu or mobo ....specially true for amd cpus and mobos.....
The only two chipsets which support bothSLI and CrossfireX are X58(Core i7) and a dual cpu solution called Intel DXS5400....
There's no other such solution yet....
Look for the chipset in the mobo irrespective of amd or intel ....either it will be amd or nvidia....if its nvidia...it will support SLI...or else CrossfireX....this is how amd mobos work....so look for the nvidia chipset on an amd mobo if you want SLI....
Hope it helps
