1680x1050 is one thing. On a 24" (1920x1200) panel, even an 8800GTS 320MB will not cut it. I ended up going SLI simply because of the higher resolution when I got my new display.
IMHO, yes, you should upgrade, or try to OC the heck out of your current chip. I am not too familiar with AMD, or what chips are good clockers these days, but check out one of the Black Edition chips. I think there's a 5000+ that is pretty darn cheap, and can run at 3+ GHz.
The 4000+ will not prove to be too much of a bottleneck for most games that a re 1-2 years old, but for newer games, and ones on the horizon, you need more power.
