Crossfire doesn't add vRAM together. You'll still have 2GB.

You're much better off with a 970 than with two R9 270's.

To 'complete 4GB'? You do not 'add up' vRAM in SLI/CrossfireX. You would still have 2GB as the data is mirrored on both cards.

That said, at 1080p and you want to move forward, I would grab the 970 and sell the r9 270 you have. That way you get on the amount of vRAM you need moving forward.

thnx for reply that was fast ....well i guess ill go with the 970 and will have to wait until they are available again.
