Hello everyone i m new on this site. so please ignore my bad english. few days back i configured a new rig with following components

amd fx 8320
asus M5A99FX PRO R2.0 Motherboard
8 gb corsair vengeance ram
single sapphire r9 280x dual x gc
corsair hx 1050 psu
3 tb wd hdd
120 kingston ssd
cm haf 912 cab
corsair h80i

after configuring and using for 3 months now i feel my gc r9 280x dual x is not that good as compared to other brand r9 280x. So right now i feel to go for crossfire two r9 280x.

My question is can i crossfire my sapphire r9 280x dual x with other brand cards or should i buy another sapphire r9 280x dual x. Is there going to be a problem if i crossfire my gc with other brand 280x.

On second thought should i sell my r9 280x and go for a new r9 280x or 290 0r 290x. But selling my gc now is not a good financial option,

Best solution

Yes it will work with other brand R9 280X cards, the only difference might be if the clock speed is different on the new card, both cards will run at the lowest clocked cards speed. But what screen are you using at what Hz? At 1080p/60hz it might be a little overkill to CF two R9 280X. Anything higher than that (etc 1440p/60Hz or 1080p/120hz) and it would be decent to CF.

Just remember spending extra money on a OC, superclocked or anything like that card, would be a waste because the cards would downclock to the same speed.

i m using a 22inch monitor with 1080p at 60hz.
So selling my gc and going for a new one will be a real waste of money. i think i should wait and in coming years maybe crossfiring my gc with another r9 280x will be a good option.

Am i right?

Usually, the simplest solution is the best - and crossfiring is not the simplest solution. That being said, cost effectiveness has to come into play somehwere - and buying a second 280x is a cost effective option and your system (and psu) should be able to support it.

While buying two of the same brand would be preferable (just for looks... ;)  ), you can CF two 280x cards regardless of the maker through the Catalyst software. You can set each cards clock and memory rates to the same values so they're evenly matched, and remember, its necessary to set them to the -lower- of the two cards (as in check both cards settings and then take the faster one and drop speed to the slower one).

Yea rather wait untill the R9 280X get a little cheaper and where you actually need it to run games well. if you added a secound card now you'll just going to use more power, more loud pc, and CF problems. You won't have any pros in most cases since a single card can run most games at 60 or close to 60fps, which is the max of your monitor (60Hz).
