Here is an AMD Radeon R9 270 graphics card sold by Sapphire which I tested sucessfully in a Windows 10 system. It was released late in 2013 as a mid-range graphics card, with 2GB of 256-bit GDDR5 RAM. It draws up to 150W TDP and requires one 6-pin PCIe power connector. Its dual fans and large heatsink make this a double-width card with two DVI-I dual link connectors, an HDMI port and a DisplayPort on back. There is one CrossFire connector on top.
The graphics card you will receive is the exact one pictured here. I include only the card. I do not include any documentation or software.
I guarantee that this item will arrive working and as described. I offer free shipping within the U.S. and a 30 day return privilege.
