After 10 months of waiting I finally got a BFL "Jalapeno" ASIC that is supposed to work with 4.5 + 2 GH/s. Currently, it hashes away with 7.6 GH/s. It's pretty noisy, though. I already took off the case and will replace the cheap fan with a NOCTUA one. Pretty exciting. At the current difficulty I will have my first mined BTC after about a week.
