Upgrading video card enough for current lot of PC games?

u need a whole new computer.

Yes, probably a new machine.
However, let's assume that you have neither the cash or the inclination to upgrade.

I'm assuming that this machine contains an AGP slot, rather than PCIe.
In which case you could get better performance by picking up an AGP 4670.
Whether this will 'be enough to play the current batch of first-person shooters out there on my PC' is open to debate.

Some would say no due to the CPU limitation. But you'll be able to play things you had no chance of playing on a 9200, albeit at reduced details and resolutions.

Your CPU would limit how good a graphics card you could utilize. You can buy any one that fits you just can't use any but the very slowest to their full extent.

I've got an X2-4800+ CPU which is considerably more powerful than yours and the fastest card I can possibly make use of us the HD4770. In fact, I have a couple games that run my CPU at over 90% meaning for those games I can't use much more than my HD3870.

There may be some games you can play with a graphics update but none of the main titles.

oh dudee..!
