Ive narrowed my choices down to these..
1. http://www.newegg.com/Product/Product.aspx?Item=N82E16814121370
2. http://www.newegg.com/Product/Product.aspx?Item=N82E16814133326
3. http://www.newegg.com/Product/Product.aspx?Item=N82E16814130570
Which would be the best choice for around $200
also are the 6850 or 6950s a better choice/ why are they cheaper?
