Hi,
I was wondering if someone could tell me if there is any difference between the GPUS below, ive bought a CNAC version but i got a CDFC version instead:

XFX FX-787A-CDFC
and
XFX FX-787A-CNAC

Any difference of the Version of the 7870 GPU?

Some websites give them different specs?

Any advice or help would be great fully appreciated.

thanks!

You are lucky, the CDFC is the Tahiti LE card, it's more powerful than the CNAC, which is a Pitcairn gpu.
The Tahiti card can xfire with any 79++ series card, and also with the newer r280 and r280x..

One last Question,
the CDFC requires 1x8pin and 1x6pin. I have done a little research using **GOOGLE** but cant find whether the 7870XT would be ok using 2x6pins (missing 2xpins).

I thought of using the CPU 8-pin connector and just use a 4pin connector for the CPU instead...not sure this is a good idea thought:(
