Greetings and thanks for reading.

I'm in the process of building a new PC and would like to ask for some help concerning the purchase of a double-precision Nvidia card for PCI Express 3.0 x16.

It's been over 4 years since I purchased my last Nvidia card and am having a hard time finding one suitable for this project and my pocket.

Just for your information, these are some of the parts I'm thinking of getting so far for the new build, so things could be changed a bit:

ASUS P8Z77-V LK LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS
Link

Intel Core i5-3570K Ivy Bridge 3.4GHz
Link

G.SKILL Ripjaws X Series 8GB DDR3 2133 (PC3 17000) Desktop Memory Model F3-17000CL9D-8GBXM
Link

Not sure if I should be looking into faster ram to be able to overclock this chip pretty well, suggest please!

If any of you have some suggestions or recommendations for this new build, please let me know!

There are so many Nvidia cards to choose from, but which modern double-precision one would you recommend for this system that will no go over $350.00 and will crunch plenty of units for this project, if any?

I might also wait for the next Intel Tock cycle to see what new things come out of it and just build then.

Any help, suggestions and comments are welcome and appreciated.

At that price you would be looking at a GTX-660 Ti.

They currently retail at $300 in the US.

Thanks for your quick reply, arkayn! Looking into it right now.

BTW, would you happen to know if there is a web site with information on which graphics cards are double precision capable?[/quote]

All of the Fermi and Kepler Nvidia cards are double precision capable, they just do not have quite the capability of the ATI/AMD upper cards.

On Milkyway and Collatz AMD is king, while on SETI and Primgrid Nvidia rules the roost.

I've been reading up on the GTX-660 Ti card and its Kepler GPU architecture. It seems like a very promising card for my purpose and also reasononable in price. I think it is a very wise suggestion and one I appreciate a lot, thanks!

Isnt the 6xx series not extremly DP cut?? Is a pcie 3.0 card a must have in your build cos it offers not that much more power at this time. Dont know if he wants to compute MW too..

All Nvidia cards suck at DP, except for Tesla.

The biggest thing for Kepler is slightly better performance for less power consumption than the 500 series.

PCIe 3.0 is also backward compatible with 2.1, 2.0 and 1.0.

Greg the memory speed is not a factor in crunching speed but it IS a factor in your pc performance. MOST Boinc workunits fit into the L2 cache of a cpu or into the onboard memory of a gpu, so SYSTEM memory is only used to switch workunits from one to another. In short if your system is to be a Boinc only machine don't spend money to get the high speed memory it won't use very much anyway.

And OH MY GOODNESS does an Nvidia ROCK at DistRTgen. I have a 560Ti that is doing 213,848.00 RAC and STILL GOING UP!!! I am doing a unit in 1,994.72 gpu seconds, 26.71 cpu seconds and getting 8,758.00 credits!!! My AMD 6850 is taking about 3937.64 gpu seconds and still getting 8,758.00 credits per unit.

This is to be my main computer at home, not just for crunching all the time. This is why I want the advantage of being able to get some fast ram for it, so that when I overclock the CPU, it will not be starved for speed because of slow RAM.

Not sure what RAM to get that will be a good match for the CPU and motherboard...

Then I would get as close to the top end as I could get, this is what your link says:
Memory
Number of Memory Slots 4×240pin
Memory Standard DDR3 2400(O.C.)/2200(O.C.)/2133(O.C.)/2000(O.C.)/1866(O.C.)/1800(O.C.)/1600/1333
Maximum Memory Supported 32GB

I don't know how much of your budget is left for memory but I would get at least 8 gig and more likely 16 gig minimum and as fast as you can afford. Do some research on the board and how to use the O.C. stuff though, not all boards handle that without manually changing the numbers. You said it has been 5 years since you built your last one, go big as it could be another 5 years until the next build. BUT remember that memory is expandable and more CAN be added later on as it becomes cheaper. You could buy 4 4gig sticks now and then as more money comes in upgrade each to 8 gig sticks.

Thanks for your information, I'll be doing some more serious research into memory for the board I'm planning on buying come next weekend.

As you mentioned, I think I will go with four or maybe eight gigs of RAM to star with and add more later on.
