[QUOTE=firejuggler;294308]so around 35 a day, 150 GHz day/day. one more precision if possible : which cpu?[/QUOTE]

One core of a i5-2500k @ 4.2 GHz, no other processes running. Only single channel memory though, don't know if that matters much in this case.

I was just wondering if your 680 was 'underfed'

You forgot the 74% load, which would take it to a hair over 200, or a bit less than what a GTX 470 can do.

Edit: With that performance, if I were BB, I think I'd take the card and sell it on EBAY, since the scarcity seems to be driving up prices.

I primarily bought it for gaming, so I'm not really disappointed :)

GTX 680 performance is horrible for mfaktc and CUDALucas. Updating my [url=http://www.mersenneforum.org/showpost.php?p=294283&postcount=1126]previous post[/url], relative performance of various compute versions using 2.1 (e.g. GTX 560) as a baseline:

CUDALucas:
compute 1.3 = [color=darkorange]82%[/color]
compute 2.0 = [color=darkgreen]137%[/color]
compute 2.1 = [color=blue]100%[/color]
compute 3.0 = [color=orangered]56%[/color]

mfaktc:
compute 1.3 = [color=orangered]54%[/color]
compute 2.0 = [color=limegreen]150%[/color]
compute 2.1 = [color=blue]100%[/color]
compute 3.0 = [color=red]33%[/color]

[QUOTE=BigBrother;294314]I primarily bought it for gaming, so I'm not really disappointed :)[/QUOTE]It also presents a good opportunity for those who want to get (more) into mfaktc / CUDALucas: a number of gamers will be trying to sell off their GTX 570(s) and/or GTX 580(s) at quite reasonable prices so they can upgrade to a GTX 680. A used GTX 570 could provide excellent price/performance for GIMPS if you get it at a good price.

[QUOTE=James Heinrich;294327]GTX 680 performance is horrible for mfaktc and CUDALucas. [/QUOTE]

This is somewhat surprising to me. I guessed CUDALucas would be bad because it does FP64 in 8 special computation units rather than the more numerous CUDA cores (an effective 1/24 FP64 speed). However, I thought mfaktc would use the more numerous CUDA cores to do the 32-bit muls and adds that predominate in TF. Where did I go wrong?

I just picked up a GTX 480 for $125 :D

Newegg has new 580s for <$400

I'd stay away from Galaxy or Zotac...

The reviews seemed good. You've had bad experiences?
