Was planing on building a computer. Had a few questions on finding the right motherboard. My plan was to get an Phenom II x6 and putting in 2 Nvidia GTS 450 so I need it to be SLI compatible also I want to put in DDR3 2000 memory in it. I was planning on buying an ASRock M3A770DE motherboard which seems to have everything I need but it says its crossfire compatible so it being that will SLI work on it too. Alrighty hopefully someone can help me thanks.
