Question on bigadv

I have my i7 970 going for a couple days now, and I'm doing around 30,000 PPD with it at stock settings. I'll work on OC'ing later, but I'm not doing the -bigadv yet ... How many more PPD can I expect by changing to this?

I also have 2 empty PCIe slots on the mobo, so I'm thinking of buying a couple cards to do some GPU folding ... Is it worth putting in 2 GPU's and losing the CPU cycles? I'm looking to spend around $800 to get 2 nice video cards. Not sure what to buy yet.

This machine is for folding only, not doing anything else on it.
 
You can expect up to around 50k PPD from running -bigadv units on an overclocked 970. As for the video cards, frankly, I think you'd be better off spending that $800 on a second i7 rig to run -bigadv units on. You'll get more PPD out of that.
 
My 970 gets right around 45KPPD on bigadv. OCed to 4.15.

For reference I get 25KPPD on normal SMP. But then I'm running 3x GPU Clients, 2xGTX570 and a GTX260. These more than make up the difference that they cost me in PPD from the 970. If you are going to GPU fold in addition to SMP fold, go big or don't GPU fold.

I think this is probably doubly true when you think about the power bill. you'd need like 3 gtx460's OC'd to match an OC'd i7 rig, that'd be a good amount of electricity
 
My personal opinion - don't run video cards at all, and run bigadv. If you really want to maximize poinrs, run Linux with the various tweaks. My 970 @ 4.35 is putting out 76.6K ppd right now on bigadv.
 
I'm with Musky here. If you have a dedicated folding rig you might as well run Linux bigadvs and no GPUs. There's a lot of guys who can get you started with Linux if you have no experience.

I'm not one of them. :(
 
Definately get that thing doing bigadv if you want to increase your production. The Gulftown in folding2 is currently running at 3.6ghz, and is producing around 40-45k ppd so long as it doesn't get stuck with a 2684. While not everyone overclocks, these Gulftowns do appear to overclock very well so long as you are running good cooling for the cpu. I probably have the lowest clocked Gulftown on our team at 3.6ghz, but mostly because i'm still one of those old school people who try to keep the core temps running no hotter than the 60's or low 70's at most in the summer.
 
Thanks for the quick replies ... I just turned on the -bigadv, so we'll see how it goes!

For the OC'ing, I have a Cooler Master 212 Plus (what a monster of a size....) ... So I'll play around with it this weekend and see what I can run it stable at. I'm running around 45 degrees C now, so we'll see.

Once I get the OC stable, I'll work on Linux. Its been about 5 years since I ran a Linux box, so hopefully it is like riding a bike. :)

Heh, if you think that CM 212+ is big, you havn't seen anything yet!

You should check out TJMagneto's Noctua NHD-14 as that is what you call a monster. When you are overclocking, just remember that F@H literally requires 110% stability. Just because on overclock is Prime95 stable, doesn't mean it is folding stable as many of us have found out. I myself found that an overnight Prime95 stable overclock on my Bloomfield was not folding stable. You might want to try stability testing with the Intel Burn Test as an overclock that is overnight stable on that will likely be 99.99999% folding stable.
