HD 5750 crossfire. Which gear can i pair?

Hello to all community, technicians and other people too.

i have an ASUS EAH5750 Formula using ATI's 5750 radeon gpu.
This model was manufactured with different pcb circuit and stock clocking by ASUS.
In our days i cant find this model (not manufactured yet)
My inquiry is given as follows:

Can i pair this Formula (already own) with a XFX or Sapphire model that using the same chip(5750) (in many cases though, there are differences on clockings from manufacturer to manufacturer).
So, will this work as crossfire and is 100% compatible? what is your experience on that technical issue?

I'll be glad to hear any suggestion or opinion on that.

Thank you for your time,

Latest news..

To anybody that he/she can read this thread. I am finally happy cause i have another Formula in my hands (ebay - about 34€ including shipping). Anyway good news stop here.   Unfortunately Crossfire without a bridge (or 2 bridges possibly) is looking not possible. As we saw to the table above this doesn't seem to be a problem (no bridge at all). Both cards working well as single vga's so it can't be physical fault or lucking functionality. The only thing i noticed is that the "ebay" vga has one step version backwards at its BIOS. When i try to change BIOS from my original vga(latest and pre-installed from the manufacturer) to "ebay" vga (i saved and programmed it using ATIWinFlash tool), i see only black screen. Then i downgrade again (same tool) everything is fine but working on a single vga (first PCIe x16 only and not crossfire)

Any possible solution of tech gurus?

Any help appreciated

My specs (my PC with both 5750's up but without bridge connection)....Thank you.

Any 5750 will pair with any other 5750, but you really should not unless you can get it very cheap.

Thanks for your reply black_zion. i think you have a point here.
sure the price is an issue..i'll check some prices on e-bay because no card of these manufactured anymore..
Maybe some more info from someone who has already a combination of the cards would be helpful.

ATI/AMD has released a table where the "5750" chip was compatible with "5750" without bridge. Also compatible with "5770" but only with bridge.

i'll let community to en-light me with its experience.

Some editions do not require a bridge, and they can't be paired with versions which require a bridge, but with the HD 5000 series not being DirectX 12 capable, the R9 270, which has a little more power than dual 5750s, is the better choice.

For future reference, here is the entire CrossFire compatibility chart covering a wide range of our Graphics Cards.
