GPU2 vs. GPU3: which "uses" more CPU resources

post #1 of 11
Thread Starter 
I'm planning a -bigadv 2600K rig, but will also have a GPU on it. Which of the clients uses more CPU resources?

Oh yeah, GPU is going to be in the 9800/250/450/460 arena.

Gpu3 client is known to use more cpu resources. They also have cards that get a lot more ppd though and using the -smp 7 flag tends to help.

I plan on running -bigadv with this rig, but I'd hate to leave the GPU idle....

Just run -smp 7 -bigadv and you'll be fine running a couple of 460's or whatever. The 2600k overclocked should have no issues with bigadv at 7 threads.

That's what I like to hear. I guess I keep forgetting that the 2500-2600K line can OC to 4.5+

The GTX 460's are great cards to fold on. My two did normally run around the 50-55oC range. Adding a GTX 480 to the mix changed that .

Eh, the actual GPU isn't important, I'm more worried about running -bigadv then getting good numbers on GPU, that's what the sig rig is for :-)

GPU3 handles resources better than GPU2.
The only thing is if you are using Fermi cards it will be harder on the CPU than other cards.

In your case you have nothing to worry about if you use -smp 7.

Haha I know what you mean, but when I think gpu3 my mind automatically goes to fermi cards

Maybe I'll pick up a 260 for cheap, but use the GPU3 client....
