Well Danny, it would certainly help to upgrade your GPU. Though I will make this disclaimer: without knowing your full system specs, as Junkie laid out in his previous post, it is hard to determine just how much help it will be, and therefore difficult to say if the expenditure is going to be worth it on its own. I will recap an example for you by laying out my specs, so that you may post your own.
CPU: AMD Phenom II X4 955 Black Ed. 4.0Ghz (OC'd)
RAM: OCZ Fatality DDR3 8 Gigabytes
GPU: ATI Radeon HD 4890 1 Gigabyte DDR3 (x2)
OS: Windows Seven Ultimate 64 bit
Game version: Current
That is basically what one would need in order to answer your question. Have a great day!
Do you allso have an UnCurrent Game version??;-)
I would suggest you for about 150€ the ATi Radeon HD 5770 or if you prefer nVidia the GTX260.
Best what you can get for the budget you told us here.
Depends on the rest of your system though. If you own a cpu below a Core 2 Duo with 2.4Ghz i'd suggest upgrading that one to, as well as your RAM if its lower than 2-3GB.

I'm running a GTX260 and it's brilliant. Recommended!
