Need Recommendations on a New Build

[Mike029]

Pardon my bias. I'm living vicariously through this build thread.

WAAAAAHAHAHHAHAHAH!!! I hope I don't let you down.
@Scole, I'll look at a dual boot setup.

I feel like Bryan is going to jump in and mention ProLasso any minute. I'm note sure if this is why their would be a performance hit but I can migrate or set affinities.

Process Lasso is a utility that allows you to force specific programs to run on a physical core to avoid hyper threading performance hits. The performance hit running virtual box on dual cpu systems is different. Bryan has good advice about both.

[Mike029]

ProLasso is one of the better utility programs out there for us in this hobby. I also use it during gaming with those finicky games. Props to Christopher Herr on introducing me to ProLasso.

Well, my experience with VM's is that Virtual box does fine as long as you don't assign more cores to a VM than a single CPU has. Once you go over that, VirtualBox doesn't handle it well at all. But below that threshold, it's not such a huge amount of overhead. Maybe a couple of percentage points. (2-4% for me.)

The one thing dual cpu systems aren't good at is crunching under a VM. It works, but there's a bit of a performance hit. If you want to also have a linux option, you should consider a dual boot setup.

With regards to VM versus native Linux, my I7 3930s take a 12.5% performance hit running under a VM. The dual Xeons take a 28-30% hit .... VBox does NOT handle multi-processors well! The difference in Mumps' numbers and mine may be because he runs cores and I run hyper threads.

ProLasso will not control VBox ... everything else yes, VBox no.

Just a heads up, looking like the i7-6950X might have 10 cores/20 threads and be available 1h 2016. It should also be compatible with the X99 chipset, same as the i7-5960X. Same base clock speed too.

Great, you had to add this to my thread? Now I have to save up some more money and wait another 6 months.... Thankfully I'll have my new 24 threads to play with while I wait.

Ok, I'm setting this up right now and have a few questions. How hot can these cores run, what is too hot? Is there a way to up the fans? Hyper thread or no hyper thread? I'll be doing updates for awhile now so I have nothing but time. I'm running PG right now to test the temps.

[scole of TSBT]

In the BIOS there's a setting to increase the minimum speed of the dual rear fans. Keep the case closed for the best air flow. Temps on my systems run 70-75 but since Tcase on those CPUs is 81C I let them run.
