I've also been offered a 6950 for about the same as the 5970 although it's nowhere near as powerful as the other cards. I'll have to take a look into the cost of a new case if I opt for the larger cards and extra cooling. Currently I'm sitting on just a stock standard 7750, so it's a bit of a change. I ended up getting an 800W power supply when I put my PC together though for some silly reason.
The only real reason why I was opting for those cards is the fact that they're cheap. However, after all the cooling and modifications I'd have to make to my PC, I'm not sure that it would be very cheap.
