It wasn't until I stuck my 9600GSO into my I7 machine that I realized the stat page was misleading. I would look and go wow, 3 295's that was spendy. Well after putting my 9600 in with my GTX260 I noticed it now tells me I have 2 GTX260's. So a lot of people showing multiple spendy cards may have 1 fast card and a couple Cuda cards of any sort.
Just wasn't sure if everyone realized that when looking at stat pages.

Just wasn't sure if everyone realized that when looking at stat pages.

I'm not sure if everyone realizes ;-), but there have been several threads (maybe at the BOINC dev boards too) about that problem. IIRC, it's a matter of the CUDA drivers, unless there's a difference between what BOINC manager says and what the "Computers belonging to ..." pages tell. I'm assuming that you speak about those pages when saying "stat pages."

Computer sind nicht alles im Leben. (Kleiner Scherz)

SETI@home classic workunits 3,758
SETI@home classic CPU time 66,520 hours

It doesn't bother me just makes it hard to compare machines at the •Top computers page. If I add another faster card I just need to add it in slot 1 and it will show that I have 3 of those. I hadn't seen the threads so I figured I would say something.

BOINC displays all of your cards as whatever your pirmary card is, or soemthing sorta like that. So yes you could have your primary GPU as the lowest end CUDA card and then 3 of that fastest things on the planet. Then everyone would wonder how those old cards as so fast.

Hey I like that idea....EDIT, next time I take my machine apart I will have the fastest 9600GSO's out there....LOL

or you could pickup and old GeForce 8400 GS for your primary.

And when you see machines with 4+ GTX 295's.. there's a way to split the card apart to make it appear like two cards, since the GTX's are actually two separate cards on one PCB. If you did not care about the performance hit with video games, you should be able to use the drivers to split one into two.

Not sure what all it involves, or if it can be done on-the-fly or needs a reboot. Ask the hardcore crunchers who do it..they can tell you.

Anyone have any idea how much faster RAC wise a GTX 275 would be over a GTX260?

PNY - NVIDIA GeForce XLR8 GTX 275 896MB GDDR3 PCI Express Graphics Card

BFG - NVIDIA GeForce 260 GTX OC MAXCORE 55 896MB GDDR3 PCI Express Graphics Card

This is my GTX275 startup info.STOCK

Don't know about the GTX260 but there is a thread with all the various card data.

Can anyone give an approximate RAC advantage?
The reason I need to know is I gave a computer to a friend and he is heading to bestbuy tonight and will get me either. I don't want the more expensive if it isn't much bang for the buck. The 275 is about $35 more.

All you ever needed to know about CUDA cards: Wikipedia

(link drops you in at the 200 series, including 260 and 275, but the others are all there too).

Guess it is all about Gflops so I guess the 275 would be best as 200 Gflops should be a bit.

Well it doesn't seem to matter to Boinc which order you put the video cards in the machine. At least with mine it says I have 2 GTX 275's even though the 275 is in slot 2. Oh Well....

it depends how hardcore cruncher you are.
from my point of view i just made today one big mistake.
i bought the EVGA GTX275 FTW for 254€ performance around 10.16 min/wu.
i bought some weeks ago a Gigabyte N26OC-896I gtx260 for 158€ which does 12.36min/wu.
the tests have been done on the same bunch of wu's

if you have an free pci-e slot an powerful enough powersuply and are going for the credits i would say try to squeeze some extra cash and get 2x gtx260.
better solution then one heavly oc gtx275 or standard clocked gtx285.

I traded an old cruncher for the card and my friend insisted on getting me a 275. That was what we were talking about at the time and then he felt I just wanted to save hime money so we went online and he ordered me the card he thought it looked cool with the 2 fans. LOL

I think I agree with you, if getting card mainly for Seti you will get more bang for your buck with 260's. So unless you get it for free go with the 260's.

which does 12.36min/wu

I have a GeForce 9600 and get between 5:36 and 33:18 for the latest 4 cuda wu.
So I don't think measuring min/wu is a reliable performance measure, the work involved per work unit is just too variable.

the tests have been done on the same bunch of wu's

as i stated above. the test where made on the same wu. so yes it measures exactly the performance of the two cards.

I now feel the GTX 275 is the better bang for the buck if it is overclocked and refurbished...My GTX 275 frozr is within seconds of my GTX285 and both are overclocked to max. Wish I had bought 2 of the MSI 275 while they were on sale...
