I also will not provide any

Provisionally none, but I'll probably pop in my GTS8800 and see if it actually measures up to the task. Modern cards are more expensive than buying multiple new systems. I simply can't justify that kind of expense.

@ the folks who said "none" can you share why you would not consider crunching with your GPU?
----------------------------------------Modern cards are more expensive than buying multiple new systems Much like any other component in a PC, you can always find options that cost too much and then those that make much more sense from a $ / performance perspective. There are many very very strong crunching GPUs available that are much less expensive than a complete system. Can you give us some more details of the the GPU/ CPU Systems you are comparing? |

If the minimum GPUs I have now will work better without raising my electric bill than I would consider using them. AFAIK the only project that was being considered for GPU crunching is HCC and that project will be finishing shortly. My position for now will be to wait and see.

What a waste! You could get 300,000 credits a day fining cures for CRC/HIV with that lot. Did you know that you can have Boinc stop crunhcing when a program (game) runs? It's more a question of heat generation than worrying about performance while gaming. At the moment I don't want to risk shortening their lifespan. If/When I build a new PC I would likely be more open to running GPU tasks on this particular machine. That is at least a year or two down the road however. There are several programs out there now that will enable you to control the gpu's to the point that they produce very little extra heat, MSI Afterburner is one of them. Running your gpu's for Science when you NOT gaming should not reduce their life span, much like running the cpu does not reduce its life span.   |

Can you give us some more details of the the GPU/ CPU Systems you are comparing?Considering the sheer volume of GPU options, most of which can't do reasonable GPU computing, how about you make some suggestions of which cards you feel are best. I've been doing distributed computing since before GPUs were capable of folding. I remember when F@H first started utilizing them and I watched the pricing model of 2nd and 3rd generation cards suddenly change. Now that there is a market for outdated cards, the prices simply don't drop. This is especially true of cards that have good computational output. I can purchase a mb/cpu/memory combo (to me this is a complete system) for under $300 for an 1100T or under $430 for an i7-2600K. This compares very favorably with most adequate cards.

And most $200 GPUs would run rings around a i7-2600K.

They suck massively compared to a CPU in processes that run in serial. The best demonstration I ever saw was a modified paint gun. One process was able to shoot colors similar to a dot matrix printer and draw a picture while the other process shot hundreds of rounds simultaneously to draw a picture instantly. The difference is the line by line method could draw anything you wanted with minimal programming, the all at once required hours and hours of laboriously loading specific colors into each cylinder and could only print that design. In effect, you could have as many of one specific picture as quickly as you could possibly desire, but if you changed anything even the smallest amount the speed advantage vanished. It's more effective if you can watch the video. As others have said, when your solution is a hammer, every problem starts to look like a nail. GPUs do wonders at rendering and at crunching numbers (think Collatz), CPUs excel at multi-purpose variable tasks. Distributed computing volunteer since September 27, 2000 |

And before I see something else shiney and wander off from my original point, my prediction is that the whole concept of CPU and GPU is very quickly becoming a dinosaur. The trend of including all processes in a single chip is only going to continue and accelerate as the technology improves.
