Hello,

I have 2 cards that I'd like to choose, however which one is the best for gpugrid?

I looked at the recommended gpu page but am still confused. Thanks.

According to https://en.wikipedia.org/wiki/List_of_Nvidia_graphics_processing_units a GTX770 uses a Kepler core rated 3213 GFLOP and burns 230W. A GTX960 uses a Maxwell core rated 2308 GFLOP and burns 120W.

The Maxwell core is a little more efficient than the Kepler core but not by enough to make up for the 1.5x difference in FLOPs.

Purely from a GPUGRID perspective, I would go with the GTX770 if your power supply can handle it.

Ah, thanks.

So I see that the minimum power supply is a 600 watt and I have a 600 watt. I'm thinking of staying with this 600 watt, or should I go higher?

Will having that card with my 600 watt power supply affect anything?

A quality 600 watt supply is more than enough for almost any system with either of those cards. Heck, it could probably run them both along with a typical PC. The "minimum power supply" requirements the GPU manufacturers post are very conservative and assume you have a low quality power supply.

Does your existing power supply have enough PCIe power plugs to run your card? The 770 probably wants two. The other thing I would check is how many 12 volt rails you have on your power supply. Does the sticker on the side of the PSU say things like "12V 50A" or "12V1 15A, 12V2 15A"?

I would not hesitate to run either card in modest system with a quality single rail 450 watt supply that had the necessary connectors.

I would have no problems using the 600W power supply, assuming it is relatively new and has the proper power cable to attach to the two power sockets on the card.

You did not say what cpu and pci-e slot you have. Both cards are pci-3 3 version and will do better if motherboards supports it. I have a GTX 770 card myself and my 600W power supply works well with it. If the associated cpu or the pci-e bus is version 2 or lower, than you get less computation than it is capable of, but also will draw less power than the rated 230W.

I do not really know that much about power supply's and all i know is that mine has enough connectors for the 770, yes. My power supply is a corsair cx-600m.

I have a intel core i3 4160 3.60ghz cpu and how do i tell what version my pci slot is?

My pc is a lenovo h50-50.

Your CPU has PCIe3.0 integrated so the slot is the same.

I don't recommend to buy a GTX 770 (or any pre-Maxwell) card. If you already have one you can use it, but don't invest in outdated technology.

That power supply will run either card along with your system without breaking a sweat.

My pc is a lenovo h50-50.

That system should have no trouble keeping either card cool although you MAY need to add a fan to the 120mm opening in the back if there isn't one there already.

I agree.

Thank you all so much for the help.

I have an idea that I'd like to share with you all but this might be a bit crazy... I just thought of it right after I wrote this thread.

I want to get a couple of dell optiplex 745 minitowers (around 50 bucks each on ebay) and stick a gtx 750ti in them, and then run gpugrid on them. I know the gtx 750ti is not brand new but it will help me so much to use the dell pc's factory psu instead of me buying a whole new one. What do you all think of this idea?

According to its technical specifications, this is a very old hardware. The Q965 chipset is 10 years old, it has only PCIe1.1, and quite slow. I have some DQ965GF motherboards from rolled out office PCs as contingency reserve, they are really slow even with Windows XP. I would get some first generation i3 desktops, they are much better than this Q965 based scrap.

A few more gotchas.

A 750ti is a great card. They were a workhorse for GPUGRID for many years. That is, until sometime last year when they stopped reliably meeting the 24 hour full bonus threshold. I have moved all mine off GPUGRID and will be reusing that motherboard / case when I have budget for better cards.

That optiplex, in addition to an ancient chipset and slow pcie speeds can only take single slot graphic cards ( http://en.community.dell.com/support-forums/desktop/f/3515/t/19611739 )and I have serious doubts on that case's ability to cool even a 750ti, much less something better suited to GPUGRID.

Here is the gpu I mean

http://www.newegg.com/Product/Product.aspx?Item=N82E16814487024&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-Video+Card+-+Nvidia-_-N82E16814487024&gclid=Cj0KEQiA_fy0BRCwiLaQ5-iFgpwBEiQA884sOan9hErx9DuRK_cBtsudF_8O_334rdyV637SVJcIGUMaArsD8P8HAQ&gclsrc=aw.ds


So my main concern is that it will be held back by my pci slot?
