Free 3 day shipping in US.
This graphics card is an AMD competitor to the NVIDIA GT 1030 to the best of my knowledge. It has more stream processors and a larger memory bandwidth (128 bit vs 64 bit) which helps it run games better, even seeing +20 fps in some games. However it uses more power and gets hotter (and possibly louder) which is a consideration. It also doesn't overclock well, though at stock it still can beat an overclocked GT 1030.

To do the rebate you must print out and fill out the rebate form, print a copy of your receipt, cut the serial number and UPC code off of the box of your graphics card, and mail it in to the rebate address, before they send you a $10 rebate card. It kinda sucks to mangle up the box, but for some reason they want you to do that.
