PC Graphics

[Kampfzentrum]

As you all know GPUs are incredibly hard to come by. I'm building a new rig and cannot even put a newer GPU in it, so I'm going to use my old card which is a Sapphire Radeon Nitro R9 390. I figured why not Crossfire it, but the mysterious AMD recommended Crossfire Compatibility Chart is nowhere to be found. Sooo... 

Will my...

Sapphire Radeon Nitro R9 390 8GB 512-Bit GDDR5

...be compatible with a...

Sapphire Radeon Nitro R9 Fury 4GB 4096-Bit

And would it even make sense to Crossfire?

Lol, NO! 

You can only viably crossfire/SLI GPUs of the same generation with the same amount and type of video memory. Preferably of the same class (390 with 390, 7970 with 7970, 3090 with 3090, Titan with Titan), unless you want to have a great deal of headache with third-party multi-GPU tweakers.

OK, thanks.
