So i have a gigabyte 7970 gpu atm and i will be getting a r9-280x to crossfire with that.

I have ordered 2 new monitors i got one today and will pick it up once i leave work.

So my question is that games on bigger resulution uses more vram.

So how much vram does games use on 5760x1080 res on ultra/high settings use?

And as i understand when you xfire/sli cards the vram does not dubble?

So do you have any use at all from the vram from 2 cards or is it still like running 1 card only that your games run better but still wont affect vram at all?

Running two cards indeed won't affect the VRAM, as they store the same information in their ram. It's impossible to say how many vram a game is gonna use, that depends on too many factors, but my guess is you will be fine with those cards in xfire.

so you think 3gb vram is good enough for 5760x1080 on high/ultra settings?

I seen most ppl that run xfire/sli and most nvidia cards are 2gb cards and they run games fine on 3 monitor setup and as 3gb on normal cards is max i think it should be good enough?

Same if i would get a 6gb model of the 7970 that wont work either as it would mirror the other and still only be able to use 3gb? so both cards would need to be 6gb models?

Yup. You should be fine with 3GiB VRAM.

If you wanted to go to 6GiB, you'd need to replace both cards.

yea thats what i guessed dont wanna repleace my 7970 since it still is a really good card so would be a waste to change it cos would not get like any peformance boost thats why i will get a r9-280x to xfire its much more worth it and out peforms any singel card, even when xfire/sli can cause more problems then a single card.

Thanks for the help : )
