I am also amazed at the speed my WU's get crunched on my video cards!
I am messing with my overclock settings, and watching my WU times. But both of my cards are averaging between 4:35 and 4:48. Though, I just changed my OC settings on my cards a bit, so the times may drop by another second or two.
And each card seems to be doing WU's in the same amount of time. Which is great. and this is only with the 8800gt. Also is great, because as the OP said, his GTX260 does a WU between 2:40 and 3:20 minutes. So my two 8800gt's are doing roughly the same amount of work as a GTX260. I'd LOVE to see the speeds with a 280, or a 295.
Once I get a really good idea as to what my average speeds are on the GPU's with my OC settings, I'm going to do a few other things, such as turn off the Aero theme and such, and see if that makes a difference at all.
I remember us overclocking, and buying new processors to knock off an 1+ hours off our WU times. Then it changed to knocking off 10 - 15 minutes per WU. Now, it instantly jumped all the way to us paying attention to how many SECOND it takes. With my OC settings, It appears if I have knocked off about 20 - 25 seconds from my WU times. And if you do the math real quick, If you have 5 min WU times, and you knock off about 20 - 25 seconds from every WU...then that gives you 1 more WU every hour ( on average. )
12 WU's an hour ( at 5 min. per WU ), and knock off 20 seconds per WU ( 12 x 20 = 240 seconds which is 4 Minutes ) and if you can knock off 25 seconds per WU, that gives you a full 5 minutes, which in that case, is more than what a WU takes to compute ( on average. )
Naturally, this all depends on how often the computer is at idle, and how much your video cards are working. But you guys get the idea.
God, I love doing everything possible to run seti faster and faster.
