I have recently bought a computer. It's a Dell optiplex 9010 with 8gb ddr3 ram and a 3.4ghz processer. I want to put in a graphics card as I want this to be a really cheap gaming PC. I want a graphics card that can handle running warthunder at medium graphics. Its got a 250w psu currently with no power cables for a graphics card. I've done some research and realise that I may need a new psu if I get a graphics card. If anyone has any recommendations on a good cheap graphics card and power supply if required I would love to hear. (I'm quite new to PC building so try to not be too complex lol)
