I have been looking around for a s775 mobo that uses ddr3 a lot since my asus striker ii extreme is dead, but the problem is there are none available any more... which lead to my question, do manufacturers still make high-end s775 mobos that uses ddr3 ram anymore, if they do who does still stock them?
Depends on your budget really. My Mate still uses a Asus Rampage Extreme mobo, thats 775 and DDR3 and is very good at overclocking.
There's the 790i Motherboards that you can look into. Or the Asus P5E3, and the Rampage Extreme. This is of course assuming that they're in stock. Or You can sell your CPU and buy a P55 + i5.
