No, not a good deal. Apparently the TR2 series has problems, and Thermaltake doesn't make good PSU's anyway. a quality 750w should handle 6970's with ease, and for sure 560 Ti's or 6950's. This is an excellent PSU for the price: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371049&cm_re=antec_750-_-17-371-049-_-Product
It's only $5 more after rebate and $30 less before. A much better PSU anyway.
Hope that helps!
