VRAM Usage - 6970 (2 GB) vs. GTX 580 (1,5 GB) vs. GTX 580 (3 GB)

[Kankkis]

If crossfire is supported i think it uses whole cf card memory, i have 5970 2mb

If it not supported it uses half, why even put 2gb if allways only half is used?

That 5970 doesn't help you a lot. Even when CF starts to become supported - you will still have 1GB of VRAM at your disposal. It will run "twice as fast" but you won't have twice as much of VRAM.

As if you're running 2 x 1GB cards. Their total amount is 2GB, but this accounts for speed only. You might as well have an Nvidia card with 1GB or VRAM right now.

This is why single GPU cards have the advantage here with CoD. 6970 2GB and 580 3GB are currently the best cards you can get for CoD.

Nah, I have seen picture from someone with a 5970 from the setup from ROF, he had 2 gig memory which he could use.

I don't know for sure, but dual GPU cards might have their memory shared (like in they both can access it all, so the data can be loaded through all memory, not separated for each GPU in its own memory). I need to check this.

yet, I would say do not buy no new hardware at least 1 month from now on. there's no point in doing it without knowing the engine's behavior after the few initial optimization patches.

I am certain that in SLI your memory doesn't double up.

That is the best advice right there.

If i put max graphics setting on rof it shows 51% video memory usage, so there is must be more than 1mb then.

what;s your setting mate? SLI with how much vram on each card? Can you do an AIDA test, please?
