Hey, A friend of mine has just bought a new Dell. It's a decent enough machine, i5-4460, 8GB 1600Mhz ram... The thing only has a 300W PSU though! It comes with an NVidia GT 705 graphics card, which as far as I can tell is pants. I know there are graphics cards that don't need additional power (the 750 comes to mind), but I don't know if that would be a good upgrade or what... Can anybody make a recommendation? NVidia or AMD, I don't care which... It just needs to be as good as it can be! Thanks!
