I am looking to upgrade my computer before the end of this year and was seeking some advice from others. I have €500 or so to spend and would more than likely be using Newegg [irish Version]. I was leaning towards upgrading my GPU to a GTX 980 or R9 Fury [undecided]. Suggestions?

 

SAPPHIRE Radeon R9 Fury - €472.99: http://www.newegg.com/global/ie/Product/Product.aspx?Item=N82E16814202157

MSI GeForce GTX 980 - €415.99: http://www.newegg.com/global/ie/Product/Product.aspx?Item=N82E16814127834

Go for the Nvidia card. They have better driver support, and I heard that the R9 has some screen tearing issues.
