GPU is too old..
You can't even play most PC games around and after 2004 - 2005 so what made you think you could use Dolphin. The FX5500 has poor SM 2.0 support, it isn't even proper and most PC games that use SM 2.0 won't render correctly and any games that use anything newer than SM 2.0 will just fail to boot completely. CPU is also single core (based on P4?) so even if you could boot any games, performance would be crappy.
Just stick to playing on a Wii or GC, or buy a Wii/GC if you don't have one. You would be looking at a major hardware upgrade, practically a new system which would run more expensive than a Wii/GC.
