Dual 580s in SLI or 2 5870s in crossfire

That's just showing us the hardware math, (memory bandwidty, core frequency, etc.) and not what they are going to do in COD. We're going to have to wait to see what hardware does what in-game.

I realise both systems are over kill but my next computer will have to last 5 years+

Any help from tech guys?

He111 be careful not to compare apples with pears, have a look here:-

http://www.tomshardware.com/reviews/...rd,2857-7.html

Those results are backed up by other reviews (I spent 3 months looking at them before buying my new PC in December).

If you have the money to be thinking 580 you should be comparing it with the 5970 or even wait until the AMD 6990 comes out and gets some reviews. I'm not saying I recommend AMD, in fact I bought Nvidia 570 instead of AMD 6970 for my own reasons, but the 6990 should be pitching at or above the 580 performance.

Essentially the difference between the AMD 58xx and 69xx series is the 68's use lower power and deliver far better tesselation performance (although CoD doesn't use tesselation). The 69xx series will push the 58xx series down in price but at the level you are considering the 58xx series is not the way to go IMHO.

CPU's dont really need drivers as we know them for GPU's.

There is no game that will give you a problem/conflict with a AMD cpu.

I havent used eyefinity myself, so I cannot comment on that.
CPU drivers I never said anything about. I was just saying the options were gpu's and I thought he misunderstood that.
2 580s can run 4 monitors and are muc more powerful cards, SLI is also more efficient then crossfire when you scale them (tomshardware).

Also, SLI/Xfire is for people who want to game at huge resolutions or on multiple monitors. A single card of the next generation will typically outperform 2 cards of the previous generation in an SLI/Xfire configuration, and do it cheaper as well.

Wait and see before you drop come coin!

Edit: Found the post by luthier http://forum.1cpublishing.es/showpos...&postcount=241

P.S. Note that i never said if the performace gain would be 1 fps or 100.

The reason Luthier cant awnser the "how much gain will Sli/crossfire give" is because A: the game aint finished. B: There isnt any Sli/crossfire profile for CoD out yet, since the game aint finished. C: Asking Oleg and team to run any kind of configuration under the sun to save us a buck is kind of crossing the line into lala land.If people want sli/crossfire to give a 100% boost i suggest you all contact NVidia/AMD right now and put the pressure on.

I would however be extremely surprised if at least Sli didnt get a boost since Oleg stated they worked with NVidia



Anyhow, i think we are digressing from the original question.

You dont need driver support to test an SLI setup, you can create your own profile, the reason why the Devs have not done this is beyond me. However being that this is a very similar engine to Il2 the GPU will have little effect its the CPU that will show the biggest performance in game.

How about utter lack of a multi-GPU system in their office or with beta testers? It's one possibility.

If you want the rig to last five(5) years, atleast get something with a decent DX11 performance. GTX580 all the way. The 5870's DX11 performance SUCK. And they've already been replaced by the Cayman 69xx gpu's.

@TreeUK, how exactly is CoD:IL-2's engine "very similar" to IL-2's?

First: They have more important things to do than making sure u/we buy the right hardware. Its not their job to do so. The sooner u understand this the sooner u can move on to your next pet peew.

Second: Similar engine to IL2? I know u just loove to take digs at oleg and team but lets keep it real, your creditability benefits greatly from it if u do. (in fact, i cant recollect a single post from u where u havent, in one subtle way or another taken a dig at the dev team).

That is incorrect. Il2 is highly CPU dependant because the engine was developed at a time when GPUs were very weak but CPUs were relatively powerful.

The new engine has been developed in an era when usable CPU power is bottlenecking, and GPU power advances unchecked.

As for building a 5+ year system, here's a rough visual representation of why this is a bad idea.

As you can see you are really paying through the nose for those last few FPS that you're not going to get with a $1000 system. But! Buying more often for a more reasonable price yields better results since that $1000 system the next year will trounce that $3000 system, and probably have more features and options. Plus you're getting a new warranty as well.
