Find My GPU is a project made for Harvard CS-50 and was inspired by labgopher.com. Using this site allows you to enter search criteria for the GPU you are looking for. You will be presented with a list of results from Ebay's search API.
The site is still under construction. Soon, it will have the functionality to grab shipping price and other information from different APIs, as well as have options to change the order in which resuilts are displayed.
Please note that not all sellers on Ebay include all of the information about their items, and that information may or may not be accurate.
Also, Ebay's APIs seem to be struggling at intermittent times, if you receive no results, please wait a few minutes and try again.
