crossfire question (please help)

[Prateek Pradhan]

Will I be able to crossfire a r9 280 and a r9 280X on my MSI B85-G43?

CPU = Pentium g3258

RAM = Kingston HyperX fury 4gb

PSU = corsair VS 650

THANK YOU!

if it's anything like SLI, then no.

again, i'm an SLI guy, not a crossfire guy. just my 2cents.

You shouldn't, you should crossfire the same video card e.g. 290 with 290 not like 290 with 280.

Apparently you can, according to people on this thread.

But it says it is not compatible on AMD's charts.

But really isn't saying much, as it's just showing that it can only be crossfired with the same card.

You can. 270 can go with 270x. 280 can go with 280x. 290 can go with 290x. AMD has allowed similar cards to Crossfire for a long time.

 

Edit: I'm pretty sure you can crossfire the 270x with 7870, and a 7970 will CF with a 280x, so ya.

 

Edit2: The 270 and 280 series are rebranded 7070 series cards. The 290 series is the only new GPU. I'm guessing the 380x will be a 290x rebranded.

 

Edit3: Important note: The 280 will hold back the 280x some. The 280 has 1792 stream processors and the 280x has 2048.

Thanks alot "JESUSARIUS REX" {I already got a 280 for a cheap price } I'm planning to buy a 280x next year because I think 280 won't be available then. Thanks again!

Wont the Pentium bottleneck the crossfire though? I know for a fact that the G3258 bottlenecks a 280X.
