I've been quietly watching for something along those lines. I've had difficulty tracking some down, which I take to mean that if some can be found, they won't be cheap. I have additional car expenses that keep popping up and it's cutting in to my "WCG toys" budget (things aren't breaking, I'm swapping engines and keep finding performance modifications that need additional parts to keep the engine from exploding. If anyone's familiar with superchargers and air/water intercoolers, PM me please?)
Well desktop crashed, and a buddy of mine is planning to move up here and bunk with me once I find a place. That way living will be easier with another income.

Holy crap man, sounds pretty bad. Hope you get transitioned over soon.
I'd invite you over but my family wouldn't take kindly to a stranger from the internet coming over and saying I invited you to live here.
Yes, Linux period point blank. LOL Also if you need links for anything for the build let me know. I have leads on just about everything for a few more 2p 1366 rigs.
Eh, it's so hard to tell when parts are failing which one it is. I've got it narrowed down to either the PSU or the GPU. The PSU is a 550w of above average if not super high quality, but it has been under loads of i7s and overclocked i5s with OC'd 280xs and GTX 770s for 4 years. I wouldn't be surprised if it is on it's way out. On the other hand the GPU is a refurb that's been folding and gaming for a year now, so it could just be crappy quality from the factor giving out. *sigh*
Any opinions/insights on how much boost frequencies help when crunching? Assuming there's no thermal issues, how often does a dedicated cruncher see boost clocks?

I do 75% as a rule for the first year. 2/3rds for 2 years or more. That one was less than a year old.
At any rate, it's capacitor aging you need to worry about, not peak vs load numbers. I haven't seen those on anything but crappy products for a long time,
I too hope you get a good place soon man. You need a better living arrangement for sure.
Mine has been running full out for the past 4 years. With capacitor aging it's probably nearing the end. I'm probably drawing almost 450w out of 550w. ¯\_(ツ)_/¯ New parts are so expensive though. $139 for a PSU that will last a while. It's a good investment, but not one that's easy to get to in the first place. Then again, if it's the GPU it wont fix anything and I'll have to buy a new GPU. To keep this thread on topic I might make a new one and link it here.

Threw together a little chart based off the CPU compatibility list for my HP Z600. Should be valuable for anyone else looking at a Xeon 5600 series cruncher.
Assuming processors can not be overclocked and will run boost clocks 24/7, here's a little chart to compare Xeon 5600 series CPUs. Variables are for my specific region, but all formulas in my spreadsheet use those variables, so I should be able to easily give out a customized list if anyone's interested. All wattages do not include anything except processor wattage. I should be including some constant system wattage in the formulas since two systems with 50w CPUs will consume more than one system with a 100w CPU. I'll see about updating this later. (Edit: Done) (Anyone know how much wattage to add for mobo/mem/HDD/etc? 30w?)
Legend:
Code:
HT = Assuming 30% performance boost from having HT enabled. Total freq is multiplied by 30% in HT-enabled CPUs. Pulled this number from my dealings with HT, but open to suggestions on more realistic figures.
$$$ = Current eBay prices (non-ES chips)
Total freq = Boost freq * cores * HT (rough indication of BOINC performance, same architecture, so should be accurate)
Freq/100w = Total freq / TDP (very rough indication of power efficiency, probably inaccurate)
Freq/$$ = Total freq / ebay prices (performance per dollar)
1 yr cost = eBay prices + power bill (CPU wattage + system wattage / psu efficiency * math to convert to kWh * $/kWh)
2 yr cost = eBay prices + 2x power bill (CPU wattage + system wattage / psu efficiency * math to convert to kWh * $/kWh)
Freq/1yr $ = How much performance each dollar gives you after 1 year of work (more is better, this is the result I'm most interested in)
Freq/2yr $ = Same as above, but over a two year period instead. Procs that are more expensive to buy, but use less power will start taking the lead eventually.
Notes/Conclusions: E5640 wins price/performance after 1 year, E5649 wins price/performance after 2 years.
Updated to add 30w to all calculations (estimated power consumption of mobo/memory/hdd/etc). E5649 squeeks ahead for both the 1yr and 2yr price/perf. Should factor in eBay prices for rest of system too. Might change the rankings yet again.
I'm using TDPs, so these are probably all wrong. I might try an overclock calculator to get a better estimate on actual CPU wattage.
Seeking input/advice on:
Typical wattage of system parts (mobo, memory, hdd, etc)
Real-world wattage of listed CPUs
Performance increase with HyperThreading on vs off
