Hello, I own a PC with a *crappy* asus ipibl-la motherboard, a random 450w liteon power supply that apparently has 80+ bronze but its quite an old psu, a Q6600, 4 gb ddr2 ram and a 9500 gs. I am looking for a budget-friendly graphics card that wont overkill. My friend is offering me his old HD5850 but I'm afraid my PSU wont power it and it doesn't support DX12. I don't want to run everything on ultra, I just want to be able to play some games like LoL on ultra with locked 60 FPS.
