I currently have 2 R9 280x is in crossfire and i am really thinking about getting 980 ti. The reason I want to upgrade I want more fps and I am tired of scaling issues(I am still debating between 144hz 1440p monitor or 4k). I used to have 4 way crossfire but I sold 2 280x already. I really dont want to spend more than 1000 on gpu. I am almost tempted to get 2 R9 390x aahhh but the scaling. The rest of my rig is a 4770k, asus maximus vi extreme, 8gb ddr3 2133mhz, and a antec 1300w platinum psu(I used 2 to power all four cards originally lol) Any input would be a appreciated is it worth upgrading or should I wait for something better to come along?
