If you're like me, you want an AMD chipset for price/performance ratio and Nvidia because you're biased and lean more those guys for gpu needs. I also wanted to SLI and there are few few mobos that will sli AMD chipset. Nvidia's website gave me a list and the Asus 750a M4N75TD was a pretty solid choice for just dual SLI. The processor was about 200 (it's the 1090t 6 core processor) the mobo 100 and the video cards were about 500 dollars together. Compare that to the intel 980x which is 1000 dollars. But as the others stated, it's more about budget and my rig came to about 1400 with a full tower coolermaster case, two monitors and some razer gaming peripherals. Best of luck with your choices mate.
