If you want to play Wii games reliably and you're on Windows, just get a Dolphinbar. If you buy this, go to mayflash's website and update the firmware for it. There's an important update that switches it off when a Wiimote isn't paired so it doesn't burn out

Only 16 USD.
If you want to play GC games, theoretically any controller that Windows detects will work fine. If you don't have a real GC controller, a 360 controller is recommended.
If you do have a real GC controller, buy this

This will provide the most accurate setup. (Other GC adapters and 360 controllers don't emulate the analog sticks *entirely* accurately).
As for your system, you're fine to play most games out there in Dolphin with IR settings. I have a 770 and I was able to run Zelda: Twilight Princess at 3x IR with 4x SSAA without slowdowns.
