I think this is the 3rd time we've done this. We vote on a single GPU to target and then we all wail on them for a month or so. It's a lot of cheap fun
By keeping the challenge closed it would require people to go to XS and chat it up in the challenge thread. This isn't about winning prizes or anything, it's about having fun. So, I didn't want some random person submitting scores and none of us having a clue who/what is going on. The original format would let everyone know everyone as we chat about bashing these chips into the ground.
