Long-time lurker and used this site many-a-time for great research. However I can't find a thread comparing these 2 cards.
Basically I'm doing my first new-build in 4yrs and have sorted the specs apart from a dilemma between 2 great graphics cards. Have always had Nvidia cards, but I'm no fanboy and simply want the best bang for my buck!
if you go for the 660ti use bt shop as they sell the Asus for £176 and 7950 by msi is only £180 from overclockers but out the 2 cards grab the 7870 as Vtx3d has powercolor as a parthner improving the brand overall
