Sorry too, but your wording put me under the impression that you considered the current HCC GPU development as not sure enough or not big enough to justify your future investment.
And I could not tell you more than how things work regarding possible future GPU developments inside WCG.

bbover3 tells us CAs a little more about possible future projects but with this information I could not tell you if any of these potential candidates might use GPUs or not: it is simply not mentioned at all (whether yes or no) and since it entirely depends on the Labs will, personally, I would not base any exceptional investment on possible future projects.

Me too I am considering building a new cruncher in the coming weeks and I think I will probably choose a good average graphics card, i.e. recent and up-to-date but not too noisy, not much more expensive than the average general purpose ones, just to be able to participate and see how this GPU crunching is working. E.g. a small GTX (but maybe it will be another one ).
What more could I tell you to help you figure out what will happen?

Hey, thanks, I am glad we are back in sync, and, it seems to me, actually quite on the same or a similar page.

The machine I am considering has twin GTX 580's. That's not chopped liver; but certainly relatively modest. People have told me to look at GPUGrid, a BOINC project. They look very interesting. With only 2284 users on 2996 hosts, they are doing a whopping 339 TeraFLOPS. That is huge. Their active science is in Cancer, HIV, Protein functions, Schizophrenia. So, I am glad for the suggestion. I work on all WCG projects and about a dozen others running BOINC. So, ten new threads on the CPU plus this new ability should be enough to shut me up for quite some time. HCC has always been active on at least four of my machines. Also, Milky Way and, you know, we should all be crunching for SETI, the grand daddy of all BOINC to which we owe a great debt. They both run GPU crunching and I work for both of them.

Egad, I will need one profile for GPU with CPU@100%, one for only CPU@100%, one for only CPU@60%, and one for my ATOM powered netbook. Hey, don't knock it. It does just fine on eOn and CAS@home, plus c4cw from WCG.

Not that I really care, but 25,000 credits to go for 6,000,000.

Thanks all for the imput.

One thing to consider is the case for the rig.

Not all cases are acceptable for water cooling. A good number of large tower cases for gaming are meant for watercooling since they already have the holes prepared (for the watercooling systems that have an external reservoir) and if you don't use those holes they are designed to keep dust out.

Plus the cases can be pretty roomy so you got plenty of air circulating. Plus some of these cases have four or more 120-220 mm case fans. Several have exhaust fans on top which makes a lot of sense since it helps to draw hot air out of the case quicker.

Mine is a mid tower case with six 120 mm fans and the fans even when going full blast are whisper quiet. People even wonder if it is on. Even the newest games don't cause it to make noise. No jet engine taking off here.

Plus the motherboards that support multiple gpu cards are big since the higher end cards take up two slot spaces so a mid or larger tower meant for gaming rigs is a must.

Also you have to keep the power supply in mind. Mid and large tower gaming rigs are able to fit the 1000 w and more power supplies with ease plus the power supplies tend to be bottom mounted with the exhaust going out of the bottom of case versus onto the motherboard and cards.. Try to get the cases with the detachable power supply dust filter.

Several months and no dust inside my pc due to filter screens on all fans.

They are coming out with motherboards that can support four gpus and those suckers only fit into a few full size towers.

I would love that Tech from time to time would give us a hint on were they stand into the development of a first project that would be GPU compatible.
On a scale of 0--->10 what is the actual stand: 7 ?
