I don't think that works anymore with the latest batches of cards. Just go with a 6970, don't bother messing around with a CF setup with cards lower than a 6850.

6790 is about 15% more powerful and is a bit more power hungry, that's all you really need to know.

I don't agree with you about the unlocking. A Sapphire HD 6950 Toxic can unlock by just flipping a switch. It has a reference PCB of a HD 6970, just shaders are locked. Even the power is 8 pin + 6 pin.

Cool, that's awesome then. I did a bit of reading, it seems to be one of only a few newer cards that can.

Sapphire 'Dirt3 Edition' 6950 (Model: #100312-3SR). IMO a 40/60 chance to UnLock

As far as older reference 6950's :
GOOD LUCK FINDING ONE !
HIS - (Model: #H695FT2G2M + H695F2G2M)
MSI - (Model: #R6950-2PM2D2GD5)
SAPPHIRE - (Model: #100312SR)
XFX - (Model: #HD-695A-CNFC)
Diamond - (Model: #6950PE52G)
VISIONTEK - (Model: #900352 NOTE: tricky because as I showed above MAYBE NOT!)
ASUS - (Model: #EAH6950)
PowerCooler - (Model: #AX6950 2GBD5-M2DH)
GIGABYTE - (Model: #GV-R695D5-2GD-B)

I'm sure there are more, but I'm tired now
It's still not guaranteed, but either way the 6950s do have better $/performance.

128-bit vs 256-bit GDDR5 and a bit different chip. Same RAM clocks, about the same core clocks, same shaders, TMUs and ROUs

Put this into perspective.
6770=5770
5770 CF~5850
Therefore, 6770 CF~5850
6950>5850
Therefore 6950>6770 Cf

Transitive proper FTW.

I had a bit of a sleep on it then decided that the better option would be to get a new PSU and a 6870 then a second 6870 a little down the line. (Unless the first 6870 plays BF3 beutifuly then I wont need a second.)
