That 2560x1440 res looks really good.
And runs quite good in my old 660gtx 2Gb , about 40-60 fps avg in campaings near flot.
Even dcs runs 40-50fps avg
Next i will get 760 or 960 with 3-4gb memory.
2560x1440 is very good for sim's , easy to read gauges etc.. Targets are sharp far away. I dont miss my ex 1920x1080 setup.
More pics soon
