Re: server vs i7 setup
i dont think so.
just having 6 GB ram is plenty for gaming.
also about the gpu's adding more then 3 cards is just waste of money. i can see why someone just want the best of the best no matter the cost by adding 4 gpu' especially adding 2 dual gpu's. but adding more then 4 is just dum.
the more cards in crossfire or sli = lower increasing in performance.
stick with a real gaming motherboard. as i advised you to in another post: get a z68 or a x68 motherboard if you really want to upgrade your already kick ass pc.
