Well if it never has to swap to system memory for texture storage and such then no it's not going to be any "faster." Once again, comes back to what you are running exactly and how. You can mod games like Skyrim that will easily use a full 4GB+ frame buffer especially at the highest resolutions.

Though, regardless, I doubt NV would even release a high-end card in the first palce that was truly bottlenecked by it's bus, production costs be damned. I think their engineers know a little bit more about this stuff than Joe Forum User.

So who here is running CFX 7970s?

I have one right now, but I'm seriously considering another one so I can safely max out all my games at this resolution. But I've heard CFX is buggy. Any thoughts?

i have a 3gb card evga 660ftw that when 2.5gb vram is exceeded starts to stutter. i red somewhere that the memory controller for last 500mb vram is just 64bit so maybe thats the problem ... and the card is from evga who are tight with nvidia smile.gif

Interesting to hear this. I have the 3gb TI's but never used/allocated(before people start correcting me rolleyes.gif) more than 2.3gb. I need to get Crysis or Skyrim to see what happens.

I too am on the quest for a suitable GPU to game on my Crossover 27Q LED-P (2560x1440) monitor, just ordered an Asus 2GB version of OC'ed GTX 660-Ti, will run some tests and benchmarks when I received the card. From what I read in newegg customer feedbacks, it should have enough power to run modern games in 1440p resolution.

Crossfire (and SLI too for that matter) works better than it used to; scaling is actually really good on many games especially since 6000 series. I was very pleased with my 6850 Crossfire set up early last year but wanted more than 1GB vram. But what you ask is a very "big question" with lots of factors to consider and no one can answer it better than you just trying it out. Could always return or sell the second card if you aren't satisfied with the results for the money. Much more information elsewhere than here though; I would look at the newer frame latency studies over at pcper as well. More info below:

I'm happy with my crossfire setup it is a little buggy but only when I'm using the modded 120hz drivers for 2560x1440 and for that matter I think I installed something that is conflicting with the drivers. Anywasys I think its a good purchase especially if you already have a 7970. I got my 2 7970s around 10 months ago for 650$ and I'm still getting better performance than a titan or a gtx 780 which is the same price right now.
Let's look at your options too. You have a 7970 so you can either
Sell the 7970 and pay more money for a gtx 780
Or
Wait until the 8970/9970 series comes out
The thing is amd has already said that its going to take them a pretty long time before they release a new card so the perfect upgrade would be getting another 7970. You'd get better performance than the volcano island cards for a much cheaper price and before they've even released. This isn't even accounting for the crossfire frame time driver fixes that'll be released soon which may make gameplay even smoother.
I say go for it and crossfire

You should be a salesman, cause you just convinced me to pull the trigger lol. Thanks a lot for the input though.

But to think I'm spending this much money on a computer at the brink of summer when I should be outside all day enjoying the beautiful weather =/

Also, that said, am I safe with a Corsair AX750 psu?

It isn't the bus width alone that determines performance at high resolution. GPUs can be bottlenecked by a ton of different things internally, and I don't know of a way to actually tell what the limiting factor is. However, higher resolutions and high res textures tend to need more VRAM and higher memory BANDWIDTH. Bus width is only PART of this, the other being memory SPEED. These numbers combined give you the memory bandwidth. An OCed 7950 or 7970 will have LOADS more VRAM bandwidth than a 680 simply because it has a 384 bit bus and the speeds are pretty much the same, but I doubt the increase is really necessary; I am betting that the GPU would be bottlenecked internally by something else (like shader power or something) before it saturated 300 MB/s of memory bandwidth.
