  1. I'm planning on doing a GTX 660 SLi setup. I'm unsure if performance is changed significantly by getting a 2x PCIEX16 mobo or 1x PCIEx16 1x PCIEx4. A 2 x16 board is quite a bit more expensive, but I don't know what difference it would make.

    Side question: A GTX 660 SLi setup is a good choice, gaming performance/cost, than other options, is it not?

    Advice would be appreciated. Thanks.

    You will want a motherboard that will support a SLI setup with x16 or x8 links. Anything under x8 would hurt your performance.

    I don't know what chip your getting (Im of course assuming an Vishera or Bulldozer Chip of some sort) but I would recommend this for around 30 more because its a higher chipset and has 2 16x PCIE on it along with a third for 4x.

    Not to mention that SLI isn't possible for a card using a PCIe x16 @ x4 (or an open ended PCIe x4 slot). Nvidia driver lockout.
