I have to clean up my post seems the 1030 managed to avoid the ram shenanigans of previous x30sYou don't seem to know much about GT 1030. They come only with 64-bit memory bus and there isn't a DDR3 version, just the crappy DDR4 ones and the better GDDR5 ones. And they all come with 2GB of VRAM.
Mine is an Asus Phoenix one with already pretty good cooling, though I've put an old Accelero Twin Turbo for it since I had it lying around. And it does run many games with low details with 1080p having a good framerate.
Not able to play Youtube is pure BS, no problems at all with a 2600K @ 4.5GHz with 1080p60 videos.
I meant 4K60 Youtube, but yes it does perfectly fine at 1080p.
It's a base model GPU, that isn't exactly stellar though put up against current iGPUs. Against the HD4000 in that 4790, it's about twice as fast. Against a 630 it's kinda ehhh... Especially when you take into account Intel has some really decent video hardware lurking in there.
An RX 560 or 1050 are much better choices if you can afford it.
