Processor Speed

Hi guys. My computer's specs are:
Pentium 4 2.4 GHz
1.25GB RAM
40GB HDD
nVidia GeForce FX5200 (AGP)
Basically I want to upgrade my PC to get rid of the low frames that I always get. I want to be able to use 4X AA and get some crisp Scenery while having good FPS.
Is my processor fast enough if I upgrade to a nVidia GeForce 7600GS 256MB (500MHz Core clock, 1000MHz Memory Clock)
Would that be enough for me to put up my graphics sliders to MAX?
Cheers.
