Got mine yesterday, and it works great! I was at 320/320, not 300/300 like I said earlier. Ramsinks allowed me to go to 325 on the memory, not a good investment. The VGA silencer, on the other hand, allows me to run the core at 375 without any trouble, even after hours of play. Rage3d only allows up to 375 core, so further than that I can't say. Lowered my case temp by a few degrees as well.
