I recently bought a ready built laptop and I want to upgrade the graphics card is there a card anyone can recommend from £25 to £75ish that can play say cod4 at an acceptable frame rate. Thanks
No can do, unfortunately most laptop GPUs can't be upgraded, almost certainly including yours. If you want something that can play COD4, you're probably looking at a new laptop...
I'm sure you can manage more than that, but if COD4 doesn't work properly (dont' forget to try it at the lowest settings), then that's out I'm afraid. Most laptops can play COD2 I'd reckon.
