Is there any reason why I would not want to use a dual core processor with a machine housing 3 gt240s?

Planning on using a dual core i3 with 3 gt 240s and 64 bit Linux.
Will I see a major performance hit over using a quad core?

That will depend if your going to be crunching any CPU projects at the same time as GPUGRID but overall it will be fine. Make sure you have enough RAM 4GB recommended.

it will be more than enough for that use and more. Happy crunching.

i3 has Hyperthreading. 4GB RAM sounds nice. You've got a large budget for a budget PC ;-) Might I ask what Linux you use? You've got a really nice thing going with almost no errors.
____________

I'm currently running ubuntu 10.04. I've tried just about ever distro over the 12 years or so I've used Linux, but ubuntu has been my favorite cause its just so damn easy to use.

As far as errors go, I almost never saw an error with with my gtx295, so far the 470s have been been pretty hassle free aside from some driver issues I'm currently fighting. My GTS 250 in the htpc however loves to throw errors.

Personally I would recommend an AMD processor for a budget rig. You can get a very nice quad core for the same price as an i3.

I usually use this site HARDWARE-REVOLUTION if I need a quick refresh. He seams like he keeps himself informed of the general prices of hardware.
____________

That seems to be a decent site. They list the Phenom II x4 945 3.0GHz as the best processor at the $140 price point, which is probably the one I would recommend as well. It uses 95W of power vs 125W for the slightly beefier Phenom II x4 965 3.4GHz Black Edition, though with 3x GT240s I'm not sure how concerned you are about power conservation. Either of those processors would be a solid choice, and will outperform an i3. The more powerful quad core will leave you the option of running CPU-only tasks later on, should you choose to expand your participation in BOINC projects.

You're quoting a thread from May 2010. Time doesn't stand still. If anyone asks me about what I would feel to be good value for Q4 2010, I would probably say an AMD CPU, Asrock motherboard, or maybe even a cheap version of a motherboard that uses a Lucid Hydra chip, not because of the mixed GPU capabilities, but simply because you'd get 2 or more PCIe x16 lanes cheap(er), & NVIDIA GTX460(s), for a budget cruncher.

Right, my bad. The 945 is now $136 instead of $140.

AMD has some nice 6 core CPU, with a GTX470, you can run several tasks.
SETI@home, f.i.but if mainly interrested in GPUgrid, then a C2D CPU, is sufficient.
I do run SETI Multibeams, MB and I have WIN XP64 rig, with an QX9650 and 1 GTX470 & GTX480 and run 4 SETI CUDA, 2 per card and 4 on CPU.

Does GPUgrid, have an ATI app., maybe later, or just out of the question ;^) ?

I think the more power efficient 6 core AMD has a lot to offer, especially if you run 3 GPUGrid tasks; you can let 3 cores go into Turbo. Alternatively, their tripple core CPUs are good value.

TigerDirect made an error on their info sheet. The only Thuban core that is 95W is the 2.7GHz 1045T, all the rest are 125W.

edit: There's supposed to be a 2.6GHz 1035T that runs at 95W as well, but I've never actually seen one so w/e.

At the present time I think the AMD Phenom II X6 1055T 95W CPU offers the best value for money:

In terms of crunching performance it matches an i7-930 (which costs much more), the 1055T uses much less power (35W less), and totally outperforms anything Intel has at the same price (such as the i5-750).

Can you link to some testing or project results that prove this out?
I thought the i7-930 was still much better than 1055T for crunching.

Jumping in is what forums are all about <grin>
~80% of the performance for ~10% of the price ... nice, thanks for the link.

No dubt an i7-930 would do more work for some projects and for some the 1055T would do more work, but having read some reviews I think it’s reasonable to say they are roughly the same in performance. However, when you consider the price difference and the running cost difference I would say overall the 1055T would be the CPU to get.

I think an i7-875 has a 95W TDP, and would slightly outperform the 1055T for most crunching projects while using slightly less power, but the purchase cost is far too high (around £100 more expensive). As crunching is always horses for courses, all we can do is be generic and vague when talking about CPU crunching performance, unless we list pages of performance data for various task types.
