Actually I decided to buy for now one 6950 for my gaming needs, but since most of the time I have to spend time on my laptop to study, I will use it for mining. I found a great offer of the 1GB version with a game present, so I think I will most certainly buy it, even if I won't make any profit from mining.
That's a good way to go. I upgraded my graphics card in January, and the one I got happened to be one a good mining card, and I didn't realize that at the time since I wasn't aware of bitcoin. I don't consider that a investment into bitcoin since my desktop is my gaming rig I've built over the last few years. Getting a free game is always great too.
