My computer lags playing games at minimum!

[Stupid Old Computer]

This thing is just laggy i can't play games without them running at 10 fps on minimum settings.
Examples: Simcity 5 , Take on helicopters (Hardly runs) , Wildstar (Really bad lag)

Tried Razer game booster nothing improved.

If i was to save for a decent machine it would take me quite a long time.

I wish i could just go buy my dream machine.

I have £85 what should i buy for it?

The rig is pretty old for playing games, that's the reason.

And Lol, you don't have optical drive?

Run CPUZ to get your motherboards model so we can look it up.

If you have a PCIe x16 slot and a fairly decent PSU, then a GPU upgrade would likely give you the best results for now. But keep in mind that with a machine like this, you are just moving the bottleneck from one part to another. Replacing the GPU will make your RAM and CPU the bottleneck.

If you wanted to upgrade this machine piece by piece I'd go in the order of: GPU, RAM, CPU. But all this depends on what motherboard you have.

I do recommend to start saving for a complete new system, but try to do small upgrades in the meantime to make things better.

Also, what retailers would you be using?

The main thing to upgrade here is the ram. The first thing you should upgrade is the ram. 2gb is not enough to play games now, 4gb is the bare minimum i would run, a lot of people run 8gb and that is required now for most new games, so i would recommend upgrade your ram before anything else.
