it's a reference cooler which is probably why the price is so low and i dont know how much difference it'll make and thats why i asked.
here's the link:

The reference cooler is loud and inefficient, which leads to it running hot (95c) and it throttles to keep it from overheating. I would not get the reference cooler, you wont get the best or full performance from it. As for the XFX, the 290 performs equal to the GTX 970, yet looks to be a bit cheaper here.
I'd say get the XFX 290 as long as it's a XFX custom cooler. Or I guess you could buy the Sapphire and a GPU cooler to replace the reference one, but that will void the warranty. Probably not saving any money doing that though, just losing the warranty. The reference cooler is probably so cheap just to get rid of the stock.
