Crossfire 4890's any good?

post #1 of 18
Thread Starter 
I noticed how cheap 4890's are getting, and I know they are not DX11 compatible but they seem nice. How would they compare to a 6850, 6870, and 6950?

If I were you, I would grab another 5770 for CF.

xfire 5770s are freaking monsters and compare to and even beat a 5870. Stick with the 5770s bro.

Run cooler, use less power, overclock higher, DX11, etc etc

Do they have to be identical cards, or can I get an XFX 5770 and use it with my ASUS 5770?
