whats the best cpu that will fit into a Asus P8Z77-V LX

Intel CPU Core i7 3770K - worth selling my i5 for? will it give good points

its so easy to spend money ... but i think a better cpu for what motherboard i have now and maybe some better - lower power / cooler gpus than 470s

An i7 CPU will make a big difference for a folding machine because you have the extra threads and can run the big WU's in Linux in a VM.

As for GPU's its a toss up, the cost of buying the 560Ti would probably outweigh any saving you made on the electricity, yes they would run a bit cooler but it might not be worth it.

As Snapshot says the 560Ti is a decent card giving you a slight boost over the 470 and a slight drop in power/heat. Just don't go for the 448 version as it won't help the heat/power.

The real bang-for-buck card is still the GTX 460, the lowest power consumption of the lot, same number of shaders as the 560 (non Ti) and costs next to nothing.

I'm running a 2600K at 4.2GHz and almost 32K PPD. It'll give 34K if I take it to 4.4GHz but it's the wrong time of year to push the overclock. It's not the best chip in the world and struggles at 4.6GHz. I reckon you should get closer to 40K PPD out of a well-clocked 3770K if you run it under Linux, either native or in a virtual machine under Windows. I got at least a 10% boost by running F@H in VMWare player rather than native Windows.

I reckon the 560 Ti is the best bang-for-power consumption GPU (90% of the performance of a 570 but 80% of the power) at the moment but the 660 can't be far off and could be very interesting.

Depends if the 660 is a rebadged Fermi or a cut down Kepler, because so far Kepler has been rubbish for folding. But us you can do well out of a i7 SB, but there is a law of diminishing returns of you run Gpus in the same rig, they rob the CPU of performance.

swap my cpu for an i7 , then run just 1 gtx 470 untill winter then use both again to heat the house when cold, this saving on heating costs. I have an electric fire and in winter it gets a lot of use.

i only have a ocz 750 psu, yet im seeing on several websites the 470 draws over 300 on full load + so thats over 600 watts for both cards plus rest of my system, my psu must be on its limit right now

can you give a breif explanation on what VM is, i have windows 7 ultimate on now, i can run it on this?

VM = virtual Machine using VMWare or VirtualBox

GTX460 is better than a GTS450 imho.

PSU should be fine, the 470 draw you are seeing is total draw for the entire machine not just the card, a 470 has a TDP of 215W and draws around 214W aprox.

GeForce GTX 470

System in IDLE = 205 Watts
System with GPU in FULL Stress = 419 Watts
Difference (GPU load) = 214Watt (TDP = 215W)

GeForce GTX 480

System in IDLE = 209 Watts
System with GPU in FULL Stress = 463 Watts
Difference (GPU load) = 254 Watt (TDP = 250W)

ok well my next step is better fans an an i7, i have 2 x 140mm fans at the front of my case and you cant even feel the air coming in!, i need to replace with Coolermaster SickleFLow - 69.69 CFM

then onto take solution for gpus, no point in making decisions on them now , ill only change my mind.
 
That's a shame, I fold as much as I can during the daytime when I'm at work but I have to turn it off if I use my computer because it slows down web browsing so much.

with gpu folding?

in internet options - advanced -


tick the box that say , use software rendering instead of gpu rendering
