No, 6870s vs 460s. I love 460s and think they are better, but AMD is coding 4 way SLI just for the 6870x2. It still has done nothing and won't for many years, that money from the power would help more just giving it to them.
you may wish to reread your post then, clearly says 6970 :/
Not really the point I guess lol I like the 460 2win as it suits the purposes I will need it for, full time folding and if I need to a back up primary gpu that still has quite the kick
