That's a bit high for a (presumably used) Ti4600 -- you can get them in the For Sale/Trade forum for about $100-120. I would recommend a RADEON 9600Pro 128MB at that budget -- similar DX8 speed, much better at DX9, and ATI is generally supposed to have better 2D image quality. If you're willing to spend around $200, you could get a GeForceFX 5900NU, or RADEON 9800NP (supposedly at CC for $200 after rebate).
