I assume you got this question a million times but I can't find the answer myself. So the two cards are available to me at the same price, both from Sapphire. I play at 1680:1050 resolution and I still wonder which card is better for me. I also think of getting the Corsair CX430w PSU, but I am not sure if it can go well with the 6850. If I could OC any of them would be nice. Thank you in advance. Cheers!
