I would like to know if the 7950 is worth it, or if I should just get a 7870. Also, my friend recommends the motherboard, but should I just get the ud3h one? Will this build fit in the case I want? My final question is should I wait for any of these to go on sale, or buy now? Thank you!

Very nice build! The 7950 is comparable to the gtx 680 with the new drivers that how good the 7950 is
