VRAM usage.

[Michaeljcox24]

Wondering whether to buy a 580 for arkham city, and in the process of doing so, wondered if the 3GB would future proof me.

So I ran heaven, AA max and anisotropy max, and VRAM usage was maxing out at 1090MB

So with my GTX470 I should be ok?

How come I was only getting 20 odd fps?

low core clock? I had it at 850.

this suggests to me that a 1.5GB version, with a faster core clock @ 1920 by 1080 would be the right decision to make.

Am I right?

Ah

Running a P5Q deluxe but will upgrade when IVY hits the shores, a 3GB 580 would be a good decision purely because SLI would be optimised?
