I have currently been upgrading my old HP m9600t and was looking to finish off my build with a set of full new parts, but had a few questions. I current have added a msi gtx 560ti, corsair 850 hx (overkill I know), and corsair 600t. leaving me with the shitty hp mobo stock i7 920 and 8 gigs off ram. I am looking to upgrade to a new mobo/2500k OC/ram. How much of an upgrade would I be able to see in games and programs like illustrator going from a 920 to 2500k (probs clocked around 4.5). also is it worth it to upgrade to 16 gigs of ram since I do use illustrator and sony vegas pretty regularly.
What is a decently cheap plus good mobo for 2 way sli without all of the unnecessary things?
