will the intel hd 4000 integrated video work well displaying 1920x1080 video - or is there advantage to going to dedicated gpu? Specifically quickly scrolling thru video. I don't care about 3d games.
I should clarify that I want to be able to quickly seek and fast forward thru very hi-def pron video with very little lag. Currently have older laptop and this is pretty slow and laggy. Does the processor have anything to do with it?? Is the dedicated gpu ONLY for 3d games as opposed to hi-def video playback.
Video really doesn't take much. I use a 5 yr old laptop 1.9ghz tl 58 and a x1270 that can play 1080p no problem. It's way below any modern cpu/gpu, and can hardly even play runescape on lowest settings. The player you are using will probably make the most difference.
