What exactly does SLI/Crossfire do.

Well my general thinking was to give it a year or two for the 'next-gen' crap to come out and then upgrade my 580's. I will be watercooling whatever I buy so it will cost a bit of cash to do so it will take a couple of months saving to do it anyway.

Im just hoping my 580's don't start lagging behind too much.

I can however currently run modern games on full spec with no problem, it was just the BF4 beta that panicked me a bit. Rome 2 Total War runs perfectly fine on my machine which I believe would be a good suggestion that my PC is still ok for a year?

- performance should be double, minus overhead, but it's often less
- VRAM doesn't double
- CPU becomes bottleneck
- more likely to get driver issues
- air cooling is restricted, consider water

single card ftw imo

I can definately agree with the cooling aspect. Without waterblocks my 580s were running at around 50 degrees on idle and anywhere up to 80 degrees on load.

Since putting a waterblock on them they idle at 30 degrees and on load hit 50-55. All this is on 1 360 rad and my i7 too so once I get my second radiator in the loop I presume it will drop quite a bit more.

Erm its my GPU. I don't have a temp log for my coolant or my CPU atm.

I need to find a program to display my GPU and CPU temps on my Logitech G19, currently it just shows my 2 GPU's.

I use MSI AB to display my GPU temps on the G19, and CoreTemp for the CPU. Won't be on the same screen, but you can switch it using that cog button or w/e it's called on the KB directly.

Silly question but what exactly does SLI/Crossfire do?

Empty your bank account & wallet.......

80 degrees on a 580 is pretty good and well within spec , especially in sli.

80 degrees is even the normal temp on a stock cooler for kepler (670/680)

My 580 single hit 80 regularly, same as my 770 is now. It's a pretty safe temp, GPU's are well specced to take up to 90+
