Hello Folders!

I'm in the midst of a new build (linked in my sig) and I'm extremely interested in folding once I get up and running! I have yet to buy my CPU or GPUs though I wanted to get a little insight from the experts over here smile.gif

My current plan is for an i7-3770K and one, two, or three GPUs from the GTX 600 series.
I understand NVIDIA is superior to AMD when it comes to folding, though being a solid AMD buyer for quite some time, I'm now making the switch, and have some catching up to do tongue.gif

My question is: Is there a 'sweet spot' card/ setup that offers great PPD for the price?

I'm running 3- ASUS 23" 60hz monitors and my budget for the GPUs + waterblocks is $1500.

Thanks so much for y'alls help!

I would get a 5xx GPU, the folding client is not optimized for the 6xx series yet.

Also fold all the cards individualy,that is, no flavor of SLI is used in folding.

If you insist on folding on cards....I would go with 5** series, or even a 4** series. I know a member on here who can pull upwards of 100K on his 460 with an 8057. But that requires some modification to the client. But really, with the money you have to spend on either of those choices in your poll, I would invest in a decent 2P Opteron rig. You can pick up some 6128's for around 100 each on eBay...and a brand new 2P board for around 400, and the price to performance ratio is much better than folding on cards.

Kepler really isn't a good choice for Distributed Computing, nvidia axed compute severely on Kepler with the new architecture.

People waiting on "optimizations" for Kepler for folding are hoping for magic to be performed at Stanford.

It looks to me that this will be your main rig and it will be folding on the spare time. You also mention that you have 3 monitors that Im guessing you are going to run in Surround. If this is correct, I think SLI GTX 670 4gb will be a good compromise. You will get around 150k ppd per card and have enough power and VRAM to run any game in Nvidia Surround. I know you can better ppd with the Fermis but you will not be happy with just 1.5gb VRAM or less for running you displays.

As much as I like server stuff and multi-socket folding, I wouldn't go with anything less than a 4P board at the time being. Two 6128 would probably not fix a 8101 in time, and there is no option to OC them on a 2P board. Even four of them at stock isn't that impressive, they will finish a 8101 no doubt, but they'd use more power than a 580 while getting less PPD.

Now we don't know how things will look when the QRB comes to other Fermi units as well, but Desert's advice is a pretty good one. There are 580's (other models too, maybe?) with 3GB vRAM, but iirc they are pretty expensive. If your main purpose was folding, 580 would be the obvious choice.

arvidab is correct, 2x 6128s on a 2P board will not finish a 8101 on time. It would be a complete waste of time/money to build a 2P AMD server for folding anymore.

16 K10 cores (Phenom II, G34 Opterons 6100) at 2GHz has about the same/slightly less PPD on SMP as a 2700K at 4.9, 18 cores are slightly faster.

So I've been sitting on some 6128's for around two months now, with the hopes of eventually picking up a 2P board and finishing a dedicated folding/server rig. Should I just totally throw that idea out the window? Our maybe pursue getting two more 6128's?
