My computer died and I need a new one ASAP and I'm dead broke. I need a temporary POS to get me through for at least 6 months or so, but would like to be able to play a few games like Diablo 3 and Don't Starve. I spend most of my online time on FB and Youtube. I don't need anything powerful. I'm looking at a refurbished HP Pavilion P7-1074 Desktop AMD Phenom II x4 960T 3GHz/8GB/1TB w/Wi-Fi Win 10. Would this work? Or if I need to upgrade the graphics card, is there something I could use that wouldn't break the bank? I don't want to have to replace the power supply.
