Do you have the 1GB Palit 560 or the 2gb ?

Several weeks ago before I got my sig card I was contemplating the 2gb Palit 560 but decided against it.

I've already seen Oblivion reach 800mb without the high-res texture pack at 1920x1080, max settings, no AA/Anisotropic, It goes higher with AA/Anisotropic.

One thing we can celebrate though, Skyrim will properly support quad cores according to the devs, so there won't be a bottleneck on quads like there are when you play cycle hungry dual core games on low/mid quads.
I have the 1gb version. So you are planning on SLI just so the performance is so increased that it won't matter that both gpu's only have 1gb vram?

^That won't help actually. The 1GB bottleneck would still be there.

@OP: I've never played an Oblivion game, so IDK what to expect from Skyrim, but I'd be really, really surprised if you go over 1GB without AA enabled.

I can't picture Skyrim conceivably needing more than 2gb, I don't expect it to get anywhere near 2gb, but I totally expect it to need more than 1gb.

It's more along the lines that I just got this card several weeks ago, so purchasing a single card like the 580 that would outperform SLI'd 560's simply wouldn't make sense as I honestly doubt I'll be able to afford another 560 for SLI as it would also require a platform change, it's just wishful thinking and I know I have the option to do so if I need to. I almost ended up getting the 2GB Palit but likely any game that actually bypassed the 1gb FB BN would simply need more power than 1 560, plus, the Hawk Twin Frozr III came out 2 days before I was able to get my card so I instantly decided the Hawk would be a much wiser choice, and I'm glad I got it.

From what I understand hitting a framebuffer bottleneck drastically hinders performance, plus, I also don't expect 1 560 to actually be able to handle Skyrim even at medium settings and averaging over 40 fps at my resolution. This is pure speculation though, but it's logical to assume it's going to be a super next gen game when it comes out. So with another in SLI I gain significantly more performance as well as not having the FB bottleneck.

How so ?

Edit - I think I just answered my own question, if you SLI you don't gain that additional Vram ? it still counts as 1 unit or something like that ?

Well I think i know this one, the vram isn't combined, it'll just be two cards both with 1gb, that'll run out just as fast as a single card.

Put simply, games can only use 1 card's vram right now.

Whoa, I honestly didn't know that. SLI isn't as advanced as I thought it was then. I've never had the need to SLI though.

The instant I saw BootyWarrior say what he said logic started going through my mind and the conclusion I came to within seconds was that in SLI you actually don't gain the extra Vram and I guess I'm right.

Well this completely changes what I think Skyrim will need, I was thinking it would go past 1gb since SLI'ing 2 1GB cards would give you 2GB of Vram and would be simple, but apparently that won't help.

Now this makes sense as single cards that go past 1gb are relatively new and having more than 1GB of Vram in your system is now not nearly as easy as I thought it would be.

This also explains the comment Vemon made about having the extra SLI performance but still having the 1GB framebuffer.

*slap* again these vram discussions...I'm confident Skyrim won't use more than 1GB ram at 1080p with 16xAF, 4xAA. The Witcher 2 is coming out in less than a week and from the sounds of it that game will run flawless on current GPUs.

I got two 6970s for this and BF3, but that's just me. I would have got 570s, but the 6970s scaled better. 2GB seems right, probably only going to take 1.2 or something though.
