I'm building a new desktop, and I was wondering about some motherboard issues. First of all, I heard only nVidia boards run SLI, which I am considering in the future. If I were to go with an X38 (Intel chipset), would running a 9800 GX2 (which uses 2 GPUs together on 1 card) be an issue because it is basically SLI? (Shaky on those details). Second, how good are the overclocking capabilities on the nForce motherboards? I've heard the X38 is extremely good for overclocking, and I'm planning on E8500 cores, hopefully getting from 3.16 GHz to at least 4.0GHz. Which board would be a better option? Thanks for your opinions :-).
