Ok, for those of you who looked at the title and went "what the fuck is that?", a Cryptocurrency is a form of currency that only exists in computers. The most famous of these is Bitcoin, which started off being traded on sites like Sil Road for people to buy drugs and weapons. I mined a few back then, I had about 6 or 7 at one point but never saw it going anywhere so I sold them for $10 a pop at the time.
As of today, they're just shy of $1000 each.
My previous graphics card, the 6950 was a monster for mining. For some reason, the algorithms used for this kind of thing seem to favour AMD cards hugely. Anywho, for Bitcoins I was mining at approx 315mhash/second, but I'll be lucky to get a third of that with my GTX 770, which tears the 6950 to pieces in gaming.
I'm going to start off with Litecoins, and mine as much as I can. I'll then use the coins I mine to buy new hardware, and combined with some bits and bobs I have at home, build up a dedicated system for mining.
If you're interested in this at all, respond to this thread and I'll answer as best I can.
This is more of a personal progress report to see how it goes, but I thought I'd stick it in here in case there are others interested in it too.
