Hello, i was wondering if it was possible to crossfire 2 HD 7870's with both different speeds and different sizes. My one card is a Powercolor HD 7870 Devil while the one im getting is the Sapphire HD 7870 OC. The Devil 7870 runs at 1100 and 1250, while the Sapphire HD 7870 runs at 1050 and 1200. Both also have different sizes. The devil is around 10.83 inches and the Sapphire is around 10.24 inches. Are these compatible?
Im planning to do Crossfire so is there any good but cheap 1150 chipset crossfire motherboard? Like a PCIE 2.0 x16 or PCIE 3.0 x8?
Note that im on a very tight budget. Thanks
