WOW, it looks like they have their own PCB and everything for this. Getting to 1GHZ takes some volt mods and nice cooling. I wonder what they will charge for this guy? I bet more than just $20 or $40. I had my 5870 to 950MHz and did not see a monster difference, but I guess I didn't really test it enough for a good comparison. I think I gained 800 points in vantage, which who cares, but Dirty2 didnt benefit much, and that is probably the most demanding game I play right now. L4D2 and MW2 are cake.
