CH ProYoke/Pedals - PCI or USB Game Port - Best results??

I have a new PC with no game port (onboard sound)...I also have the older CH Products Flight Yoke Pro, and Pro Pedals, that I would like to use; they were built for a Game Port connection. I understand there may be USB to Game Port adapters that would help me get some use out of my older equipment in XP.Also there is the suggestion to load a PCI Sound card, disable the sound and use only the Game Port....Any suggestions on either avenue? which is more successful??Sound Card - not looking forward to having hardware on my PC that might cause issues...would prefer a simple PCI Game Port only card (I still have the CH ISA Game Port card, but that is useless)USB to Game Ports - I think the success rate in using them is hit and miss.....Thanks for any feedback.
