Looking for a graphics card

I bought a pc 4-5 years ago it was great but now i think the hardware is a bit out dated. Im using rx470 4gb, asus 460 steelegend mother board, intel core i5 10400 cpu, 2 x 8gb ram sticks and 700w power supply. I think that my graphics card has to be changed because i bought it second hand from a mining rig. Suggest some replacements. I am on a tight budget of about 150. Thanks in advance
