    To me, low end = current cheapest ones as they overclock to stock levels of the more expensive ones and then some ie 4Ghz+ (assuming you have a decent cooler)


    If you wanted to go 4gpu, I'd be tempted to go 980X and no folding gpu, just a cheap one for graphics (unless you're a heavy gamer) as it would probably be cheaper to buy abd definately cheaper to run. I'm not sure what a 980x would do ppd wise, but it would be very respectable on bigadvs as it's 6core, 12threads compared to the others at 4 and 8.

    Ok, all this is great info, however what about using AMD Phenom II X6 Six Core 1090T Black Edition for CPu folding, will it run BigAdvs ??

    I wouldn't think so, maybe if you overclock it heavily but even then it would be very close deadline call.

    You would also have to trick the assignment server into thinking that you have 8 cores. This is discouraged by PG in the last post of this thread.

    Okidoki, cheers guys. So looking at possible new PC build with i7. Any recomendations, I take it, it will need OC'ed to 4Ghz for good affect.

    Pretty much the recommendations from this thread ie 930/950, 980X or xeons. It all depends on budget and ppd aspirations. 4GHz is a reasonable goal when it comes to i7s and bigadv. Both power draw and and bonus rise at increasing rates.

    At home have a i5 760 OCed to 4Ghz, so thinking of building another based on that for the 450s.

    Sorry if I'm misunderstanding you but the 760 only has 4 threads so won't be able to run bigadv.

    No, your right. My fault. What would you recommend, that I can OC to 4Ghz, MB also needed with 3 slots for GPUs???

    Cheers

    Based on a guess at your budget (£700 for CPU and 3 x GTX460 GPUs???) I'd go for a 950 or as cdb mentioned earlier I'd ditch the GPUs and go for a 980X. You'd get roughly the same points with either but the 980X would use less power.

    The only 3 x double slot 1366 m/b I've had any experience with is the P6T SE which has OCed i7s to 4 GHz just fine. Someone with more recent experience might want to chime in on this one.

    P6T SE works great for 3 GPU's.

    However the tpf increase for running 3 GPU's would mean you'd need a big OC to get maximum points from a bigadv unit

    OK, new thinking. Keep Folder 2 with 3 450s doing there thing. Strip, sell Folder 1 to run 980x only:

    What best MB & mem for OCing would you recommend, band for buck ish.

    Saspro, what hardware are you running?

    Cheers again.

    I'm running 3x i7 920's, one is running at stock (need to OC again once I've changed OS) the other 2 are at 4GHz
    Each has 6GB Corsair CMS 1600MHz RAM
    I'm running 1x P6T Delux V2 & 2x P6T-SE's
    Coolers are Titan Fenrir & akasa nero's

    So, are there ANY mobos out there that could take an LGA1366 i7 AND four GTX460s? I just don't want to confuse Santa:D

    This is the plan, home PC folder 3 (2 x 460) weekend toy, stays as is.
    Folder 1 getting a WC 950 with Asus P6X58D-E Intel X58 OCed to 4Ghz.
    Folder 2 will get the CPU H50 from 1 and keep 3 x 450.

    So 1 & 2 run Mon-Fri, 3 Sat-Sun.

    Looking forward to to playing with 950 and SMP.

    Cheers for all help.:rock:

    Looks very nice. I have to retract my statement from earlier though :eeek: I now run my 860 at 3.8 GHz and it returns almost 23000 PPD alone, running -smp 8 and -bigadv flags! That is mighty 10000 PPD more then my GTX470 with recent WU's. If you'll go for i7 950 @ 4GHz then this number will be even greater! At that point I need to eat my own hat as the CPU seems like a bargain to buy and run comparing to the GPU... :duh:

    Well, all set up and OCed to 4.2Ghz. Working through prime till tomorrow mornining. So no real usage till Mon next week. As an OCed CPU at this stage, with priccess the way thay are, 950 looking good.

    Cheers.
