** ALL HAIL THE NEW HEAVEN KING - ATI 7970 3GB!! (TRI-FIRE TESTED)**

Not sure if it's just me but i'm finding these Tri XFire benchmarks pointless. Realistically how many people are going to buy 3 of them?

What I imagine most want is some non biased and honest benchmarks of:

1920x1080 and 2560x1*** running the latest games like BF3 against a 1.5gb/3gb GTX580

Then doing the same above with 2 cards.

This is a far more realistic setup that we will be using than whats being tested.

If this is possible it would be much appreciated as I take most reviews lightly.

I'm on the fence myself at the moment as i'm running a single 1.5gb GTX580 at 2560x1440 and ideally need more RAM. I'm not sure whether go for this or go for a 6990 which may drop in price a little.

well most people don't buy high end graphics cards to play games, so benchmarking tri systems is good for the 'hardware enthusiasts'

I'd like the same but with a 7950 instead

Err... What?

That's exactly what I bought my 580 for. And I'm pretty sure that's the reason 99.9% of people buy high end GFX cards for.

I mean, the only other use of GFX cards is compute and parallel processing, and if you need that then best to go with a Quadro, Tesla or FireGL

sorry I don't agree

Gamers can have just as much fun playing games with single current gen, or even single last gen cards. They just have to run in high rather than ultra. The difference, once you are fully engrossed in the game in minimal to non existent.

Those who buy triple cards are entusiasts and their primary reason for purchasing isn't games.

That said, I did say MOST people ;)

As others have said, those figures can't be accurate: A 448-bit memory bus would not operate with 2Gb of RAM (it would need to have 1792Mb, or 3584Mb). Also, the core would scale downwards in proportion to the memory bus (implying 672 cores, rather than 704).

Well it can but the last 256MB of memory would essentially be limited to the 64bit channel width of the controller it is attached too. Think of the GTX550TI which has a 192bit memory interface and 1GB of memory.

I must admit that I am somewhat disappointed with the 2560x1600 Heaven scaling Gibbo posted above. Scaling only appears to be around 41% from 1 card to 2 (assuming the 108.5 fps is from CF). Hopefully real world tests will show much better scaling (as will driver improvements and a faster CPU).

I think gibbo was running 2-3 cards with totally different settings. The first bench was normal tesselation with 4xaa and 4xaf. The second bench was extreme tesselation with 8xaa and 8xaf.

Ah, good spot. In that case it is quite impressive although still quite a performance hit in the grand scheme of things.

We can all cherry pick reviews, hardocp was the kindest toward the 7970. I put more faith in Anand and TPU which show it around the 30-35% faster than 6970, cut your garbage about fanboys.

Bit of irony in your statement there. You "put more faith" in some just the way others trust others, yet there is no reason for you to actually "trust" any of them.
