The 6950 is a splendid card. That version may also be un-lockable to a 6970, a huge bonus, I did it myself with mine. I'd go for somthing like the msi twinfrozr 2/3 (not sure which) 6950, its a great card with a great cooler, but again, not sure about unlocking it. The DirectCU2 is only, really for extreme overclocking, which you probably won't do. and anyway, the twinfrozor 2/3 overclocks great anyway. hope this helps.
sorry for the random "T" on my first reply.
