the dell precision m4600 on paper sound good but so far its not preforming better than my x230t the dell 3000 series is just junk when I got it. I couldnt tell from the pics really well that it was an i3 even if it was newer than my x230 the cpu benchmark is better bad. I got the thing for 30$ walking out the door in rough shape guess its to be expected. I have more hope for the m4600 sense it has a nvidia quadro 2gb and a boosted 24gbs of ram. in editor it can be from 15 to 50 fps depending what I am doing, I think it mostly suffers from lack of drivers for windows 10 and a spotty ssd is not helping. ill probably get a new ssd to see if that helps waiting of the e531 as it could be a dedicated gpu or intel hd junk. anyone have had some success in running unreal on older hardware?
