Not taking sides here either but let's not forget that nelly was trying to do this build on a sensible budget, yeah given he's not gonna hit 4k with his card but neither am I with my 970 which cost £70-80 more!!
Out of interest, I've been fiddling with Virtual Super Resolution and it looks amazing at 4k on the ultra preset.
Unfortunately, although it reaches as high as 45 FPS, at times it drops down to very low twenties which makes it too choppy really. At custom ultra with everything on full, it averages only 23 with drops to 17 which gets really stuttery at times and is no good on the eyes at all!
It does manage 35 consistently at 1440p at ultra which looks really, really nice too, but after running all week at 1080/60, it feels slightly sluggish. Going to try 4k with medium to high settings tonight and see if I can get a locked frame rate.
VSR does cause a slight lag with the wheel input apparently, but I can't say it's noticeable in Dirt Rally, particularly as the steering is so exaggerated whilst sliding about. It might be more noticeable in Project Cars for example, but overall a good little feature for us TV gamers.
