Searching a graphics card under 100$

you can look for 7750 OC/6770~

I'd say a 6670/6770/gt 555/gtx 260.
But you won't be able to play many games with only 1 gig of ram.

A GT 9400 is roughly 50 TDP so I guess something in that price range and power usage would be a Radeon HD 6670/6750 or if you prefer Nvidia a GT 440. I can't suggest anything higher than that without knowing what power supply you have first.

I wasn't away that the emulators would really make use of stronger gpus.

They are mostly going to use cpu emulation so Getting a more powerful gpu might gain you very little.

The 6770 would be the best card for under $100.

If you read this you'll note that this emulator has several rendering options, the LEAST efficient is a software mode using the CPU mainly, so yeah it does use the graphics card.

However with emulators it's possible that some cards work better than others so maybe some research is in order?

I don't know much about it, but I agree that the HD6770 is probably the best card for that price. I tried emulation once and gave up. At the time I could buy a PS2 with controller and lots of games for $100.
