Just for me personally, ignoring market/console wars pissing matches ... I would be OK with something double the Wii U for Nintendo games.
Wii U is estimated at 350 GFLOPS, so 700 GFLOPS with 3-4GB of RAM for games would be OK. Nintendo games already look pretty nice on the Wii U, going double I would assume would allow for a lot more 1080P games with cleaner image quality or the same image quality but graphics that are a nice step beyond Wii U. Given Nintendo's more cartoony graphical style, a little can go a long way.
Of course I'd gladly pay for like a 3 TFLOP Nintendo machine with 12GB of HBM2 RAM and all that jazz, but they likely will never make anything like that so why bother thinking about it.
