I have a Sapphire Dual-X Radeon R9 270 Video Card - 2GB DDR5, PCI-Express 3.0 (x16), Overclocked - 11220-00-20G
I want to buy a PowerColor Radeon R9 270 DirectX 11.2 AXR9 270 2GBD5-DHEV2 2GB 256-Bit GDDR5 PCI Express 3.0 CrossFireX Support ATX Video Card
Both are R9 270 model but not exactly the same.
Can I successfully crossfire the cards?
Will the results be noticeable / worth it?
Any additional thoughts from you experts will be greatly appreciated
