Just ordered GA-EP45C-UD3R & Q6600 from Newegg with plans to OC the Quad-Core Q6600 as much as possible. My question is this motherboard here supports both DDR3 & DDR2 so I would like to get DDR3 1600 or higher for it but I have heard there are some problems with P45 mobos & DDR3 especially with trying to OC? Can you make a recommendation as to what type of DDR3 mem I should get or if it even makes a huge performance difference in games/apps to get DDR3 over DDR2?!?! So confused..
