Both links provide sufficient information about my PC incase of compatibility issues.

Amongst other things I am looking to be playing GTA4 with relatively high settings.

Im guessing I will probably have to replace the PCU along with the GPU.

Just want to know what GPU to get to make sure its compatible and good performance. Including the PCU, Im looking at a budget of around £150 but dont hesitate to give me options that may increase performance.

It looks like im asking a lot but all help is appreciated. :)
 
You'll need a new PSU first, correct. Have a look atHD 5770 for the GPU. Then using the rest buy yourself a 400-500W PSU from Seasonic, XFX, corsair, antec, be quiet!, enermax, or Pc power and cooling. However, if you can extend your budget, then you could get GTX460 or HD6850 and a 500-600W psu
