I'm really rather confused by it all, so I've come up with a question or two:
- If I buy a motherboard with a PCIe x16 and PCIe x4 slot and put a graphics card in each, will they both run at x8 speeds due to the x16 being split in half, or will they run at x16 and x4?
- If I buy two ATI 6850s (let's simplify it to "top-midrange graphics cards"), will there be a noticeable performance drop from running one of them at x4 speeds. They'll be in CrossfireX (linked).
Sorry if this is the wrong place to ask this question.
