Can i crossfire a MSI 7850 and a Powercolor 7850?

[guitargod1174]

i have this msi GPU: msi 7850

and i just bought this powercolor gpu: powercolor 7850

also someone said that if i crossfire 2 7850s i could get the same performance as 1 R9 290. is that true?

the performance may be somewhere around another 2/3rds as powerful, like a total of 175% on some games. it totally depends on the game too. if you have then, id do it, if you need to buy one.. I may not. one gpu is always a preferred solution for the average gamer.

EDIT: as far as performance vs the R9 290 (not the 290X), the performance would be close. about 80% of the 290 at its best.

yes you can mix and match 2 different 7850s.

they will work well together

 

[woworwow]

If you want the performance of R9 290x then buy it.
Crossfire-ing doesn't double the performance, it will increase performance by about 50-75%. And you'll find trouble when playing most older games or indie titles

Go for the Crossfire! I crossfired two XFX Double D R9-270x and now I can game 1080p Ultra setting with full AA and AF any title over 60 fps! Just make sure your case has a VGA side panel fan to keep those cards cool, crossfire setups run hot. Also, make sure your PSU is the right wattage.

Oh, and I seriously doubt that it will equal the performance of an r9-290. LOL

close to 290x in performance if game supports crossfire that is.

Those are NOT the same cards! LOL The link has two Sapphire r9-270x in crossfire with higher core clock, more stream processors, higher boost clock and higher effective memory clock! All those independent variables are going to make a big difference in gaming!

when u run in crossfire the 2 cards sync together.

they will run at the same speed when runned in crossfire solution

From my understanding, he has an MSI 7850 and Powercolor 7850. The link you provided tested two Sapphire R9-270x cards. Although the r9-270x is an updated version of the 7850, they both have higher specs than his 7850s. So he would not see the results of that link's benchmarks because his cards have lower specs. That's what I was referring to.

thats why i derped read too fast.

sorry.

i read 270x times 2

heres the performance of 7850x2

2 x 7850 in CF would be similar to a single 280X probably a little weaker where supported,
