Going SLI Need Help

post #1 of 10
Thread Starter 
Im looking to buy 2 GTX 560's and run them SLI. My question is do I want a motherboard with 2 x16 slots or 1 x16 and 1 x8. Whats the difference? Will the card running in the x8 not use its full potential? Im looking to get the most out of this system.

x16/x8 describes the latency of the PCI-E slot, and x16 is faster than x8 (go figure tongue.gif) However the difference between x16 and x8 isn't even noticeable, even in SLI. So if you don't plan on going tri-SLI, I recommend you just stick with the x16/x8 board, it should be cheaper.

There wont be any noticeable difference between 16x/16x and 16x/8x. You'll be fine going sli.

Should a 750w power supply be sufficient for 2 of these + other hardware?

You're fine. You could probably get by on a quality 650w.

If you will be placing the SLI cards next to each other you may want to consider using cards with reference (blower type) coolers. They run cooler in SLI since they exhaust heat outside of the case.

Some none reference cards cannot be placed next to each other without overheating.

If you plan on having a gap between the cards you can choose any card you like.

Hope you SLI rig gives you many hours of gaming happiness smile.gif
