Thinking of building new machine

[Bradtech519]

Wife needs a new computer to be honest.. I am thinking of letting her use my Phenom 2 965.. Thinking I5 750/I7 860 or 1055/1090T Phenom 6 core.. What do you guys think would be best for crunching? Anymore I don't care about gaming etc..

Let me ask you this: Would you rather spend more money now on the processor (Intel), or more money later on the electric bill (AMD)?

Good point that I haven't thought about too much.. The Intel's at full load generally consume less power correct? Are there many significant increases in terms of the eight virtual cores on the I7s vs the four core I5s/Phenom IIs? I tend to want to stay away from LGA1366 due to the premium cost of the X58 chipset. P55/I5/I7 is what I am favoring right now. Even though I am seeing the Thuban X6's kicking some butt on the SIMAP top computers when you get out of server class computers and down to average workloads done.

For Folding, the i7 w/HT is the way to go assuming you'll OC to a decent speed. You'll be able to run the bigadv WUs & can double the PPD of the X6.

Both... I vote both... you can never have enough

No...My X6 does 12-16k ppd. My 920 used to do 10-12k ppd, now with the bigadv it does 16, but its not far ahead of my X6, and was behind.

And as far as power consumption, I don't have the stats close, but they are not far distant at load.

now with the bigadv it does 16

That's true if you only get the 2684, but that one is much lower ppd than the other bigadv WUs. On my system it is ~10 minutes slower per frame.

My comment was directed at the statement that the 920 W/HT could do twice the PPD of an X6. I have both, and my 920 is clocked higher(3.7 vs 3.6), and still the X6 beats it in PPD most of the time. On my old motherboard, at 4127, it was beating the pants off the 920, but I burned out that motherboard, and this one won't clock as high.

Other than the 2684 WU, my i7 gets 25k+ with bigadv.

Well, as soon as I get one I will let you know. But on units OTHER than bigadv, by X6 beats my 920 most of the time.

The 1055T has a locked multiplier correct? I am probably going to grab a 1055T and overclock it. I had a X2 3600 brisbane in the past I got up to 3100 just by downclocking my RAM. to DDR2 533. You happen to know how high people are getting these 1055T's on a good OC friendly motherboard on air?

T think over 4 ghz...There is a thread here, try a search in cpu forum for 1055.

On a board that can handle a high (286, I think) HTT freq, you can hit 4Ghz with the 1055T chips.

I'm currently running the GIGABYTE GA-790XTA-UD4 that has USB3 and SATA 6.. If I had something other than the retail heatsink I could get it a lot higher than 3.6/3.7.. My 965BE that is. Right now I just run it at 3400 default.
