If cost were not to be a factor, buy a full tower and get 4 9800GX2s on a 4 pcie mobo of your choice. A few dummy plugs and you will be pumping out some srs ppd

thanks for referencing me stinger!

if you really have that much money, i say get affordable mobos with 3-4 pcie slots and then 8800GSs/9600GSOs as they are the best bang for buck. what stinger listed for AMD is exactly like my intel version. with what i have.. i should be able push out 72000PPD on stock settings. if i OC the cards.. 80,000PPD and thats assuming 5000PPD per card but i've seen people say the've hit 5,500.
my folding farm cost me... a tad more than $2000. i mean unless you are dead serious on having it all in one case, then you would be better off buying a rack from say homedepot or lowes and place your rigs on that. i built my racks to have it somewhat fit into my apartment... so yea..

Any rig w/ 4 GPU's is going to need a little extra cooling. The MSI mobo's have double spacing between the slots. or you could run single slot cards. If you use 4 dual slot card you will have to mod the case a bit to clear the bottom card, unless you get a case w/ more than 7 expansion slots.
If you were to get 4 9800GSO's, you could get away w/ using a 500W or so PSU. Now if you went w/ 4 9800GX2's i prob would go w a 850-1000W PSU since you will have twice the cores.
Folding isnt a graphical application, per say. So you dont need all of the slots to be 16x. 8x is plenty to run a folding application.

Are there mobo's with 4 PCIE x16 slots that are all at a x16 speed? I don't understand why thats so hard to do? |

9800gx2 = (~5k per instance) X 2 = ~10k per card
for single slot? i'd have to say 8800gt/9800gt w/ v-mods. someone showed getting about 6k per card with a good v-mod.
EDIT:
this is a v-mod by CL3P20 with 8800gs's, imagine one with 8800gt/9800gt's

You are right, though you probably wouldn't get twice the PPD, because In hyperthreaded processors only part of the core is copied,not the actual execution cores. Intel says hyperthreading gives about 15-30% more performance, but I don't know how much that would be for [email protected]

Probably close to nothing because [email protected] SMP has a very different multi-core design then other applications and games that will utilize 1 physical core fully.
Hyper threading I believe only increases the efficiency. Say I am running a program that uses very little proccessing power but maybe it needs to be run in real time so that process will take one thread all the time but only use lets say 5% with no hyper threading 95% is wasted, but with hyper threading a different process can use the wasted processing power.
But because you are running the GPU client on 8 GPU cores each CPU core can handle 2 GPU's but if it its not hyper threaded it will have to switch from one to the other making an in efficient system, but because the Core i7 are hyper threaded each GPU can take as much of the core as they want and the OS/CPU microcode will handle load balancing across all 4 CPU cores.
