Dual 580s in SLI or 2 5870s in crossfire

If its for running Cliffs Of dover then bear in mind that there is no information available as to whether the game will benefit to running SLI or crossfire, no testing as been done to date.

580's without doubt

Voice of reason!

It's funny how many people are spending thousands on PC's for SOW without even waiting for the most basic of info on what runs them and how.

We've had no benchmarks, no reviews, no details on resolutions or settings, etc. The closest thing we've got is, "this pc had these specs at some show and we're not sure exactly the settings or build state of the game was". There was also a video of a leak from a beta tester and still, not a lot to go on.

Wait for some info. Maybe SLI/Crossfire is going to be great, maybe it will give you no performance advantage at all. As for building a PC to last you 5+ years, that's stupid. You spend $3000 on a PC this year, and same time next year I'll build one with only $800 and spank it silly. Building a PC every 5 years for gaming is like buying all your milk for the year in one shot. For a while you have a ton of milk, but it ends up stinking for the rest of the year.

Concur - good info.

There's not a single propeller flight sim I'm aware of that benefits from SLI or Xfire. With the cost of the extra card - and the higher price motherboard (2X 16X PCI-E) you would be taking a huge risk.

Best advice is to wait until the product is delivered. If CoD runs out of the box on either Xfire or SLI then it will be the first. Otherwise you've spent a large amount of money on performance you'll never see.

I currently have a single 5870 I purchased more than a year ago. My MB is a Gigabyte with 1 16X slot and 1 8X slot. If by some miracle CoD is xfire compatible AND a second 5870 makes a significant difference in the eye-candy I can run in real time - then I'll find a second 5870 and get a new MB.

I really don't believe that will be the case however. I hope I'm wrong.

Sli/crossfire is supported in CoD hence u get more performance with 2 cards instead of 1. If anyone want an answer as to how much, feel free to wait till the game is released.


My guess its gonna get better with every new driver version. (if NVidia/AMD will bother with it that is)

I hope your right - and I hope further it's not just SLI but Xfire too. I think your second point maybe the most significant in the actual interest AMD/Nvidea shows in the product line.

Hopefully CoD will see a bazillion copies and the world will be just perfect. On the other hand air combat sims don't seem to have benefitted from either technology.

Thanks btw for the 16X/8X info Baron.

Luthier said that SLI/Xfire was inconclusive at this time. Do you know something he doesn't? Did we miss an update?

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!

Of course they are supported! How can they be not?

Whether they offer any performance advantage is a different question, to which I don't have an answer at this time.

P.S. Running 16X or 8X makes virtually no difference whatsoever (around 3% iirc)

Now the 580s are apparently the best GPUS around (tesselation) but the 5870s have EyeFinity, which I don't think the Nivida have? I would like Eyefinity but the 5870s are older tech than the 580s!

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.

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?
