I know you get this question asked a lot, so bear with me. I am asking again because each graphics card obviously fits the system/components in each machine.

I want to upgrade my graphics card (for gaming and second life) and I am on a limited budget.

I am fairly clueless when it comes to technical details but here is the readout from my computer. I have replaced the hard drive, graphics card and added memory since we bought it years ago. But Second life is getting slower and slower the more advanced the graphics and viewers get.

I currently have installed: ATI Radeon 9550/X1050 series (which I added a few years ago)
319MB graphics memory

My computer details are:
Advent (HP)
Intel Pentium 4 CPU 2.80Ghz
1.00GB RAM
32 bit operating system
1 processing core
Windows 7 installed

I am presuming I need an AGP interface as thats what i have at the moment?
Any and all advice gratefully received. :)
