How do i know whether to change gpu or cpu

[joshua_was_here]

Hey. I have a question whether to upgrade my computer's GPU or CPU. I just need it for light gaming, such as battlefield 2, team fortress 2, halo 2, etc. I can still run them now, but it can get laggy sometimes with the graphics and it doesn't feel smooth playing them. My computer specs are:
AMD Athlon X 2 5050e @ 2.6 Ghz
Ati Radeon HD 3200 256mb
4GB of ram.
320 GB harddrive


for some reasom, my integraded HD 3200 graphics has 2.6 GB of shared ram. I think its the GPU problem because i'm only doing light gaming. Also, i only have about 80$ to spend on uprgading? upgrading to what would make the most out of my investment?

Thanks

Well both CPU and GPU are weak. But your GPU is much weaker than the CPU.

What power supply (PSU) do you have and how many amps are on the +12v rails. It would be best if you can take a picture of the PSU's sticker which list all the specs.

Also, what motherboard do you have? I'm guessing it is probably an old one what has a PCI-e 1.0 or PCI-e 1.1 slot.

your gpu is really really really bad. How to tell its weak is if you try to play a game and it lags on higher resolutions the its the gpu.
