What camera can take pictures at 3 frames per second with flash? I have a Nikon D50 Digital SLR can take 3fps?

i have a Nikon D50 that can take 3 frames per second without flash. But is there a camera that can take pictures at fast rate with the flash. Because i have to wait 6 seconds everytime to charge the flash to take pictures.....

yes im using the built in flash

I would assume you are using the built-in flash? The SB-800 flash will shoot 5 frames per second with the Nikon D2X, but I'm not sure about the D50. I would guess it would work.
