Total money spent exclusively for bitcoins: ~$350, 2x BTL jalapenos, but I wont get them til nov/dec I suspect.
other spending:
1x6870 on my fileserver which I bought with old mined bitcoins [Thanks to btcbuy!]
Sold my GTX570 to a friend for $180 and got myself a 7950 for $350. [-$170]
bought another 7950 for $330.
so totally $330 + $170 = $500 on gpus.
Why dont I call them spending? because I use those GPUs for gaming when not mining, so technically not exclusive investment in btc
