Indeed for years I ran with lower priced gear and this is why I can see budget builds being just fine. I remember running a pair of 680s when I decided to treat myself and running 3 x 1080P monitors and oddly enough, I never ran out of VRAM and that is with a measly 2GB per GPU but you insisted that it was a problem and you are doing the same now but it wasn't and it isn't and sure, for those who have the money, there is 8GB options, which makes sense.
People need to consider grunt as well as VRAM and this gets missed every time. What is the point of putting 8GB on a 1050 for instance? VRAM scales with the GPU and it makes it cheaper for the buyer, ergo 1070/80 are powerful cards, so having more VRAM to have the higher textures and AA makes sense, a 1060 with 3GB might well be right at the bottom of the choices but at £185, it is a consideration and the VRAM won't be an issue, so long as the buyer understands that it is a 1080P card and not a 4K card.
I do wish people would look at the big picture before typing.
There are options for around that money with more than 3GB, or even 4GB.
Do you have a problem with us recommending those and explaining why?
If not then the last page or two in this thread has been utterly pointless.
There are alternatives, we are explaining the reasons for those alternatives, just leave it be.
