Okay, I've managed a compromise... since I only play games on my TV and not my monitor, I don't need full surround when doing "regular" computer stuff so I connected an optical cable between the computer and receiver and set it to the TV/CD channel, that way I'll still have sound when checking websites and doing work. When I play games I turn on the TV and switch the receiver to the GAME channel, enabling the HDMI to enjoy Borderlands 2 in glorious surround. Best of all, Windows remembers which audio devices are "default" over others, so it automatically switches from the SPDIF on the mainboard to the HDMI on the graphic card. More complicated than I wanted, but meh.
The Gefen HDMI Detective would be nice to have, since it seems to convince receivers that the TV is on even if it's not, unfortunately if I could afford it I'd have gotten a higher-tier receiver instead.
Thanks to everyone for the suggestions and help.
