GTX 560 ti vs HD 6870 2GB

[9a3iqa]

To upgrade my rig from a HD 5750 which would be the best option a GTX 560 Ti 1GB or a HD 6870 2GB (know where to get both for roughly the same price with the 6870 being slightly cheaper).

I usually overclock my GPU (did it with the 5750 because it wasn't providing enough power to play BF3 ).

My specs are:

X4 955 @ 3.8ghz

8GB DDR3 RAM

XFX CORE 650W PSU

1080p monitor

My motherboard has no SLI/Crossfire support but I may upgrade to an Ivy bridge motherboard which does in a couple of years.



So in essence should I go for more power or more vram?

560ti, only get 2gb of vram if you are above 1080p

But what about in a couple of years if I want to XFire the 6870's?

560ti is faster, but BF3 is said to be starved of graphics memory @ 1080p with Ultra and msaa.
Then again, I guess neither of those cards can render Ultra /w msaa @ 1080p at 60 frames per second consistently enough to make that config matter.
