I've got an elderly friend who's into WoW. They got a Dell Optiplex 7010 but the onboard Intel video sucks. I'm showing an i5-3470, 16GB RAM in the slimline case. From what I see online it's got one PCIE slot and a 250W power supply. No power connectors for the video card. Suggestions on a decent and preferably inexpensive video card? I'll probably be paying for it and there's a chance I'll be driving to another state to install it. I've seen some discussion online of a HD 7470 or a HD 7570. It needs a vga port or a DVI I can connect VGA to w/ an adapter. If it was local and non proprietary hardware the decision would be much easier but w/ the potential of driving hundreds of miles to install, or sending it to a non tech to install the options go down.
Short because of room in the case, low profile, no power connectors, will work on a 250 PS, and VGA connector is a pain. Fortunately she's not a power gamer works decent is acceptable. It doesn't need 120 fps at 4K.
