I've been upgrading my pc recently. I already have a new graphics card and I am planning on getting the above motherboard, either a i5 2500k or i7 2600k (if I can afford it) and was planning on about 8gb ram. i've looked on the ram compatibilty list on Gygabyte's website and I'm having trouble finding those model numbers for sale. Corsair, G-skill, Patriot and Kingston come up regularly. I just want a recommendation.
