For that price range, frankly, run the component cables. A video processor is required to get decent component>HDMI conversion, and those are expensive. For less than $3k, AVR receivers don't do a good job with conversions.

The Wii and Gamecube are not critical applications, and I suppose you would be satisfied with an inexpensive conversion, but component is capable of beautiful performance. Running the extra cable is really worth it.
