The 9600 was a great card back in the day, however it is a bit dated. There are so many great cards out now depending on your psu and budget.
The AMD HD7770 or the GXT550ti are both awsome cards for around $130. If you wanted to spend a little more the GTX560 could be had for around 160.
But won't they be bottlenecked? The E7500 is still a good CPU even for today's standarts, but is it powerful enough?
