ADDITIONAL COMMENTS: I have the choice between crossfiring 7850's (2) http://www.newegg.com/Product/Product.aspx?Item=N82E168..., or a single 7950 http://www.newegg.com/Product/Product.aspx?Item=N82E168..., Still learning about Graphic's cards, so any extra information about why the other choice would be helpful, i've been stuck with this 3850 for about 2 weeks now, my 7870 burnt out, RMA'd for a refund, and now with my combined funds I have 370$, stretching allowed.
