I'm planing on upgrading my old gpu MSI R7 260 1gb to a http://www.xfxforce.com/en-us/products/amd-radeon-rx-400-series/rx-470-rs-4gb-sf-triplex-rx-470p4sfd5 or https://www.msi.com/Graphics-card/GeForce-GTX-1050-Ti-4GT-OC.html#hero-overview or http://www.palit.com/palit/vgapro.php?id=2719&lang=en&pn=NE5105T018G1-1070F&tab=ov . Which one should I get? My current component's are: CPU FX-8320 not OC, Kingston 8gb 1866MHz RAM, Asus M5A78L-M/USB3 mobo and a LC-Power 500W LC500H-12 V2.2 12CM FAN. All three cards are at my budget maximum and I can't get an RX 470 with two fans since they are like 30$ more expensive in my country. My biggest concern is my PSU. I'm absolutely sure that it can handle a 1050ti but not sure about RX 470. Note that I'll buy new PSU at start of March so will it run my new GPU till then.
