6870 CFX vs. single GTX580

It will start cramping when you try 3 display eyefinity or higher res screens. I have a mild OC on both cards and I dig the performance/$ ratio for the combo.

If you are running 1440/900 as you show in your rig, this will be a wonderful combo for the $. Your CPU could start to be a bit of a bottleneck for some newer/upcoming games, however.
Price per performance 6870 crossfire is better than one 580, still are, but in defense to the 580 those benchmarks are old. There have been two driver releases since that have improved performance on the 580 that would tighten those scores. So it's slightly inaccurate, but neither of us have proof so I guess those are good scores to give the OP some idea.

Also there is something to be said about a single card solution that's almost as powerful without having to crossfire or SLI with issues and the whole 3D gaming issues that the 580 does much better. So to lose some performance for what you gain on the other hand has it's perks I'm willing to give up some performance over. It's also very problem free since, and I'm happier gaming.

I gave up two 6870's for one 580 after the 10.0 drivers and the issues, microstutter, and BSOD from wake up, that made me jump ship along with the 3D factor I was heading toward. But it was personal decision, still dosen't take anything away from them, I just didn't have the patience. I'm glad the newest 11.0 drivers fixed things in crossfire to make things work. It's a great set up for the OP.

In no way did I mean to directly compare the CF6870 to the single 580, just showing a reference site for the OP. If I had the $ when I built this rig I very likely would have gone with a 570 instead of the first 6870.

The benches are also stock clocks, which most people don't have on this site =)

Either way, it's all about what's best for the OP in this case. And right now, upgrading the CPU/platform would be the best choice imo before worrying about a 2nd GPU.

I think your right about the CPU/platform coming first. The single 6870 is good enough to play todays games alone. The more intensive games, very few, all he has to do is turn off some eye candy. Still would be very playable and enjoyable.

I'm planning to get 1920 x 1200 24'' monitor first. But don't think my current GPUs will run that really well. So that's why I was thinking 6870s.

But how would a new CPU increase performance. I mean no games really use 4 cores right? And it just seems bit dumb to upgrade for a little higher clock. As a new upgrade also would mean new motherboard and memory.

I currently have setups with 6870 CF and a single 580. Simply put, the 6870 setup is much strong. I have and am not experiencing any issues with the 6870's and drivers.

The 580 is a beast of a card if you only can use one graphics card due to motherboard restriction.
