I don't think it's actually possible to use 3 of those cards in tandem unfortunately.
I understand it to be 4 GPU's max in Crossfire due to driver limitation, so only 2 could be used in a crossfire setup - maybe wrong though.
It will be a beast won't it. lol
@Vasskjoling, I did consider the SR2, but realised it's another £3/4,000.
I'd have to get myself top spec Xeon and two of the blighters. And I really don't think that's a pay off in performance for an increase of 50% in budgetry terms.
@_Fanatic, I suggest you look for a new model with either a very good job so she won't care. Or maybe one that doesn't spend all your money in the first place. lol
Luckily or unluckily, I don't currently have that problem. But I'm sure the gf will get her claws into my wallet at some point in the next couple of years. lol
Right back to CAD for the day me thinks.
Cheers for the heads up Xonar, I'll look further into it. But it'll definately take two cards with dual GPU's. I may even switch to four single GPU cards depending on cost.
Hehe if only... we have our first baby on the way in December so my money is well spent already, got two blighters digging into my wallet soon enough!!! No new gear for me for a little while anyway - well, that her indoors will know about anyway!
Back to your build, looking forward to seeing this go together, good luck
Cheers _Fanatic, congratulations on your soon to be new arrival. Condolences to your wallet. lol
Well I'm not going to be rushing it, I want it to be immaculate, but also give myself time to refine the design as I go.
Not only that, but I only have AutoCAD 2002 at home, and have been used to a much more modern and easy to use program when I was a CNC programmer.
So there are many features I'm yet to learn fully.
You've no idea how frustrating it is, knowing what I want to do, yet nothing is making logical sense in comparison with what I have been using at work. lol
But this is a journey after all, and you're more than welcome to join me on the ride.
No problem, I will say though, 3 5870's is probably the max you'll want to go with Crossfire as scaling becomes awful as soon as you reach 4 GPU's, in some games even tri-fire is running equal to only 2 cards.
Your best bet would be either 3x5870's or 1x5970 and 1x5870, either way you're getting 3 GPU's but depending on your budget/available PCI-E slots either option would give you a massive amount of performance for those crazy eyefinity resolutions.
@Xonar Yeah Iv'e just been going through some details, and have taken a look at the GeForce 480's To see what I can manage to fit in with some performance juggle room. There just seems to be a real lack of conclusive information about what is achievable on the board Iv'e chosen. But this will be my first triple card set up. My concept may have to be adjusted, but that's sometimes how it goes when you do something for the first time.
Have you a link to anywhere I can work out the maths?
I had assumed you were keen on an ATI setup but if you are happy to go with Nvidia also then that opens up a lot more possibilities.
What is it you're trying to work out exactly?
I just want to learn how all the numbers work really. Not being a GPU expert and not understanding fully how the threads run through the board completely puts me at a disadvantage.
But I'm always keen to learn everything I can, so that I make better more informed decisions.
I appreciate your help though, thanks.
Got a bit bored with the CAD work, so I thought I'd leave it for a while. But decided to post some old pics of my current favourite machine.
The only thing that has changed is that the iside is now painted black, and I tidied up the cabling a bit more. And also put a FJ 260Gb HDD too.
I love to drive and fly.

So today I'm getting a little bit of designers block. I think I'll occupy myself with earning some real money for the day. lol
Just found google scetchup. Impressed. I think my designers block has been beaten back into the dark recesses of my mind.
