Work saved
 
For some time I've thought that the future DC
saved shouldn't be valued as highly as the
initial LL.

OTOH, it has recently occurred to me that [B]in practice [/B]
the typical fate of first time assignments is to get
returned unfinished about 4 times before they
get completed, thereby increasing "work" saved.

[QUOTE=Primeinator;281151] I checked my GPU but I do not think that it is of the correct type to work towards the GPU effort.[/QUOTE]

What kind is it? Any recent AMD or NVIDIA should be able to contribute.

I remember he posted in another thread; if memory serves it's a (really) old nVidia.

It is an ATI Mobility Radeon HD 4670 according to my device manager.

Wait till the first of the year, then you can get a lot of GPU for just a few bucks!!! :smile:

The good news is that you do support OpenCL 1.0! The bad news is that you have to have OpenCL 1.1 to use mfakto :down:

I don't know why this is required, and would ask bdot why 1.0 is no good.

Apparently memory does not serve.

My Galaxy GTX440 was about $100 last June. I'm expecting some after-Christmas sales on not quite state of the art hardware that will include plenty fast GPUs....allowing you to pick up a decent one for a good price.

[QUOTE=Dubslow;281127]Who had the second LL completion?[/QUOTE]

It was mine.

Cross quoted from a thread in GPU Computing:

[QUOTE=Dubslow;281145]It's [URL]http://www.newegg.com/Product/Product.aspx?Item=N82E16814127519[/URL]
Hopefully that helps.[/QUOTE]

I'm surprised that all the GTX 460 cards at NewEgg are still that pricey. Cheapest one is $159.99 after rebate, free shipping. I guess I caught Microcenter in close out mode when I got mine at $99.95 after rebate. Still waiting on the rebate. This was a local purchase so I did have to pay a little over $10 in sales taxes.

I would concur in Christenson's expectation of post-holiday sale prices.
:down:
Maybe this beastie ([url]http://www.newegg.com/Product/Product.aspx?Item=N82E16814130626[/url]) would even get more affordable. Not that I would suggest it seriously. Dual GTX 460 SLI-on-a-card, minimum 46 amps on 12v. Worse, it looks sure to dump most of the heat inside the case. Bunch of hard luck stories in the reviews, too.

I don't know about what's there now, but the one I linked to I got for $149.99 (no rebate) way back in April.
