Hi, first time poster. Recently I purchased this card for my new build, but when I received it, it had 2 DVI ports, and in fact looked exactly like the 7750 that XFX also offers. Is there anywhere I can verify that I received the correct card? It said r7770 on the box.

EDIT: Here are some pictures of the card: http://imgur.com/a/eKtof

The box name?

You can also use programs like:
MSI afterburner
GPU-Z
AIDA 64
to view GPU info.

Yes by the clock speed. The 7750 runs 800/900mhz core, the 7770 runs at least 1000mhz core.

You can see the core speed under catalyst control center under the performance tab.

Thank you, my card is clocked at 7770 speeds. Do you have any idea why it would have an extra DVI port and no crossfire slot?

The crossfire finger is on the side of the card. It has gold connections similar to the PCIe side of the card only much shorter in length. That card will crossfire and it happens INSIDE the case. It is a great budget card.

Sometimes some manufacturers decide to not put the crossfire connector, and they sometimes decided on different configurations of display connectors.

I have a 6770, that is a single slot model, and doesnt have a CF connector either. Sorta weird.

some models are a little different in the connectors probably you only received one like that...

but what do you mean by no crossfire slot? i can see in your pictures there is YEs a crossfire slot to plug the crossfire bridge;

if you were referring to the crossfire BRIDGE it comes with the motherboard box if it supports it, normally it does not come in GPU box.

Thanks everybody, it turns out the card's design has changed and the description/pictures on most sites still have not been updated!

And yes, it does have a crossfire port, that's just my ignorance showing :p
