Upgraded to a Gigabyte Gaming G1 980Ti and Asus ROG Swift PG279Q about a month ago. My system was good for its time, but 6-7 years old and the 460GTX SLI setup really struggled with Horizons.
Now it's astonishing. Monitor is flawless (I was worried about reports on returns due to QA issues on early releases, but they were unfounded in my case). Key features are 27", IPS panel with 8bit colour, 1440p res, and G-Sync. Set mine to 144hz, although 165Hz is possible.
At 1440p on Ultra in space I average 143.7FPS (1.0x supersampling). 90-100 in busy stations. The lowest on planetary landings is 68-70. Never seen the FPS dip below 60 under any circumstances. Plus the G1 is still quieter and less power hungry than than the 460SLIs.
Technology has moved on! Not cheap of course but I intend to use this setup for a long time to come, and for those who can wait, it will all come down in price soon enough.
