Somedey, when I get money... Usually my current GPU acts good, I can run AC director's cut in 1080p with high(not ultra) settings and AA off with solid 20-30 FPS, Blender usually gives me 30 FPS in games I make. Yeah, but it is not enaugh when I start to make high-poly scenes, use high-resolution shadow maps(rendering them in 4K(4096x4096) uses SO much of GPU) or when I use UE4, however, in UE4 my 3.4GHz quadcore CPU looks like acting strange, but maybe it is RAM which slows down some proccesses(6GB). I am not sure why, but UE4 is very slow for me, compiling shaders almost for 10 mins, so slow building... And after UE4 I have to restart computer because he acts like he would have carried tons of stuff on his back. I don't know what fault is it! That's why I don't use UE4 for now, 90% Blender, at spare time testing out some stuff in Unity)!
