EVGA GTX660 SC
On a Q9550 with 8GB RAM. Was happily running ED at 1080 mostly maxed until Horizons came along but have managed to tweak to get around 30fps on the surface while keeping a bit of graphical niceness.
Was looking at a whole new PC with either a GTX970 or just going fill bananas on a GTX 980ti. But got distracted by an xbox at christmas and now the thought of paying around £1000 on a machine to play mostly the same games has dented my new PC excitement. May now wait to see what Pascal stuff Nvidia bring to the table this year.
