I'm trying to get caught up with this thread, there are a lot of nice overclocks in here!
A close friend of mine is building a budget gaming rig on older tech, he managed to find a P6T Deluxe V1 that we'll be cross-flashing to a P6T WS Pro, and I snagged him an X5650 today, it should be one hell of an upgrade from his current Q6600. I'm hoping that we'll be able to get the CPU to around 4.2GHz for him. Marry that with the 7970 from his current rig and it should be able to rock some games for quite a while.
EDIT: If anybody has some leads on triple-channel RAM kits, let me know. RAM is the only thing we still need.
