Can this setup crossfire 2 Sapphire Radeon HD 6970s?
My setup:
Motherboard: ASUS M4A89GTD PRO/USB 3
Processor: AMD Phenom II X6 1100T Black Edition
RAM: Corsair XMS3 4GB DDR3 (2x)
Power Supply: Thermaltake TR2 RX 750W
Video Card: Sapphire Radeon HD 6970 2GB 256-Bit DDR5 (2x)
Cooling System: *to be updated soon*
I'm not too knowledgeable in CrossfireX. I want to crossfire the other 6970 with the already existing one. Can anyone tell me if my current rig will be able to handle it in terms of power output and the motherboard being able to actually supporting 2 GPUs? Also if someone could explain 8x8 and 16x16 that would be much appreciated.
Thank you for reading.
