    So I'm gonna put together a folder/cruncher rig here soon but wanted to get some advice on socket and chips.

    1st question is 1156 vs 775. I'm not going to be able to drop more than $150 into the processor so a nice dual core 1156 like the 655k would be almost all I can afford where as I found a nice Xeon/Q9450 for the same price. Which would be better for crunching? I'm guessing the quad would do better.

    2nd is board choices. I can easily find a simple single PCIE slot board in either 775 or 1156 but I'd like to use two gpus for F@H in the future. For the 775 I was thinking of the 750i set(Evga has Bstock for $50) but I'm not sure which to go with on the 1156 side. The 1156 will need DDR3 which will be an additional cost I dont want to incur. Probably an open box less than $75.

    3rd GPU choices Right now I've got a 260 just waitin to start folding. I'm thinking about a 295 which should pull some serious ppd, and a used cost of $240 is very appealing. I'd like to have a pair of 285's but thats a pipe dream for now.
    Should I pick up another 260? What kind of ppd could I expect with 2 260's? 20k? That is what an nice 295 should pull as well, right?


    Additional components:

    Case: who cares it'll be in the garage
    PSU: will need to pick one up 2nd hand, probably a 750W Silencer or Corsair
    HDD: again who cares as long as it installs F@H and WCG and W7 I'm good :D
    RAM: Depends on the board, ddr2 1066 for 775 or ddr3 1333 for 1156 roughly 2GB
    Peripherals: who cares probably a used Dell crap; wait I think I have a wireless mouse/kb
    PPD/WU: should be awesome!

    Thanks for the help guys!

    2 GTX260's would net you 15K-16K PPD depending on work units.

    PM me as I might be able to bring your "pipedreams" to life if you're looking for used parts.

    Don't 1156 boards only run one pcie in 16x? I would go with the 775 and Xeon. And yes 4 is better than two for crunching.:)

    I would say go 1156 for upgrades down the road when i7s get cheaper and what not. I do have my GTX 275 for sale with 9k PPD production across all projects ~stock clocks.

    Well they come in all sorts of varieties, really. Standard fair is 2 PCIex16 slots that run in dual x8 when both are filled and single x16 then only one card is there. Low end is single x16 slot only. Both have an additional single x4 electric but usually x16 mechanical that runs off the PCH as well. The bandwidth limitation on the x4 doesnt limit folding :D The high end boards have 1+ NF200 chips (or even a hydra) that allow multiple full x16 bandwidth to all cards.

    Thanks guys, I'm leaning towards a Q9550 and dual 285's for starters :)

    Once I get all this new hardware I'm gonna fold for 30 days straight on my i7/470 rig as well and catch up with the rest of the team.
