Guys I have a general question about PCIe 3.0 and Crossfire.
Currently I have R9 290x and I use ASUS MAXIMUS VI FORMULA (Yes I know, I was dumb enough to buy parts without consulting anyone here at GAF
) ....
If I get another R9 290x will both work at PCIe 3.0 16 ? or will be run both at 8x and will I waste power? due to x8 bottleneck ? or whats going on ?
One of my friends said that if I get 2 x R9 290x for cross fire both run at half the speed... so I am confused as I am new to PC gaming... if the PCIe port drops to 8x is that waste the potential of the card ?
