Hello, I am building a new system and I was planning on putting an R7 260x in my MATX system and in order to fit my sound card in to i will need to put an R7 250 in crossfire with the 260x because the 250 i found from msi is a single slot and the 260x is double and my sound card is single. my mobo will live without the soundcard but it would be nice to have it if i need to run 2 R7 260x in crossfire. Any help on this issue would be greatly appreaciated. Thanks.
The R7 260X and R7 250 are based on completely different architectures and cannot be crossfired, you will need to get 2 R7 260X if you want to crossfire
not architecture, but base core, what's required for crossfire (edit: even if you could crossfire them the 260x would slow down to the 250's level, and a 260x would be far superior to 2x250)
what you could do is buy a pci-e riser for the sound card, so you can plug it into the slot under the cooler but have the card moved out of the way
if i read this correct this is a brand new system? why are you trying to crossfire entry level cards? just buy a better single card
