I'm getting a new pc with two GTX 780s in sli, a large HAF x942 case, and a Corsair H90 watercooled i74770k on an ASUS 787 pro mobo.

I'm wondering about overclocking the GPUs (Asus GeForce GTX 780 DirectCU 2 OC 3GB - I've read this is one of the most overclockable GPUs).

Would you recommend overclocking? Is it a risk? Will it shorten the GPUs' lifespans? Are there other problems?

Oh, and can it be easy to do? I've read that MSI Afterburner would be good software for this?

Your knowledge, tips, and experience on this topic will be most appreciated.

I have it and it is easy as pie to overclock, just install msi afterburner, and follow an overlocking tutorial. on the stock bios, you can max out the voltage and i personally can get +195 on the core. this may not be as high as you get, but you should be able to get within 50 mhz of that.

1. yes, it does shorten the lifespan of the card. no one knows by how much, but if you put more stress on something, it is not going to last as long.
2. it is easy and no real immediate risk as long as you follow a guide and don't try to add +500mhz on the CORE clock.

3. you'd be silly not to do at least some overclocking on beast cards like this as they overclock so well :D

4. the asus cards are built to be overclocked and to last


I love my...

When I had a single 780 I overclocked it and found that I got about 6 fps average on valley. Overclocking is not really a risk as long as you do not install custom BIOS. The cards have thermal limits that will throttle the card before it gets too hot. Overclocking has often sparked the debate of decreasing lifespans of CPUs and GPUs, although there is no proof so to say, stressing something really hard problem is not the best thing. Only other problems I have seen with overclocking is the increased heat produced, so make sure you have a good air flow and space between the cards as they need room to breath, and as they are not the reference blower model, will dump heat into your case instead of venting it out the back.

MSI afterburner or EVGA Prisicion X are good programs for overclocking, although I believe more people prefer afterburner.

OK, I think I understand: There's no risk for the GPUs as there's a cut-off before any damage is done. The problem is that there will be more heat in the case which may cause problems for the CPU and other components. This heat problem should be alleviated by a well cooled CPU and housing in a well ventilated case.

And I guess I should be OK as I have a nice Corsair H90 CPU cooler and a nice, big well ventilated HAF case.

Am I right?

Thanks, again, for your knowledge, Devballs
I see you have similar specs to my own system. I, however, will have an 850W PSU (Corsair AX).
Do you reckon that'll be enough to overclock two GTX 780s and the i74770k CPU?

You should be fine with an 850W PSU, te corsair AX series is fantastic, I just gave myself some headroom incase I decided to add more components down the road, or do a custom water loop. Enjoy the new rig, I am quite pleased with mine!
