Looking at the specs I think that your video card will be more than fine. Certainly in ED's high quality setting, Windows borderless at 1920x1080 with another monitor for ED support websites or the Forum. Short of the limits on your Internet connection, lags at sometimes in the Frontier servers, and your girlfriend or favorite pet jumping into your lap at a critical game moment you will be OK! Everything will be smooth and even instancing with other live players will work on your end versus maybe their settings are too high. If ultimate resolution, going to VR and other options is your goal than you are spending too little on this PC. Start out at £1500 ($2000.00 USA) to get there.
I'd also be concerned with the 8Gb of RAM memory and would suggest 16Gb. I've tracked my PC memory usage when playing ED plus other support websites running 10Gb. I also run ED on a SSD drive for fast loading.
