I'm running my Q6600 with a Gigabyte GA-P35-DS4 Rev 2.0 MB at the moment. I've just come into a bit of money and now getting itchy feet to upgrade! Is it worth updating to a newer board and if so which one? I am also using PC2-6400 RAM with it but I want to change that as well. My last couple of boards have been Gigabyte boards and I have always found these to be reliable.
