GPU miners 'should' pretty much all be out by now.
Yep; that's part of the reason I'm so keen to get more of these. I LOVE mining, and I just had to shut down my video cards because this last difficulty change finally made them unprofitable. I mined until the VERY end with those things.
Right now all I've got until the Avalon chips show up is my lowly 1 erupter from this first group buy.
