I am very close to buying some upgrades to my system, mostly to replace my burning up motherboard. I priced $400 for an AM3 MB with 3x PCI-E slots and the 790FX chipset, 4GB DDR3 1333@ 7-7-7-24 (with reviews saying it can do 1600@ 6-6-6-20), and a 2.8GHz Tri core Phenom 2 with the hopes of unlocking a fourth core.
Then they drop the 6 core P2 at $210 @ 2.8GHz. So for $100 more I could get that beauty, but I would need to save up a bit more. So if it doesn't perform well on big advanced units then I might as well stick with the trike for now. But I'm sure it will do just fine and I'll have to deal with the pre purchase anxiety till I have enough money! EEEEEEE!! (sorry I just got off a night shift where I drank way too much coffee)

Could some pull the ole switcheroo? Download a bigadv unit on their i7 and move it over to a PIIX6? Or would the client kick it out after it saw it had access to only 6 (real or virtual) cores?
Back in the day I had someone download me a few QMDs so I could try them out on my AMD hardware. So this is a similar concept.

Worth a shot. I mean, the PII X6 is a quarter of the price of a 980x I7.

from the benches on tom's it looks like the PII x6 is really catching up on the i7's.

Don't want to be the Guinea pig
I wanted to buy a i7-920 Then i saw the X61090T Now i want this Chip I don't want to get it home and it can't fold big Advanced units,, still thinking about it. I'm A big AMD fan .... That CPU Ram and motherboard are burning a whole in my pocket

Yeah reading around the folding forum it does indeed look like the client needs to see eight cores before you can download a bigadv. But on the plus side some people are pushing some numbers around based on what the x4 does and they seem to think the x6 with A3 bonus points should get somewhere around 12,000 - 15,000 PPD depending on the clocks.

Has anybody tried an X6 out with A3 WUs? If you assign all 6 cores to an A3 with the '-smp 6' flag (I think), are you seeing higher PPD?

At what speed? Stock 3.2Ghz or higher?
Do you have any idea how it detects the number of cores in linux? Solely for testing purposes.

Id bet it looks at /proc/cpuinfo
using cat /proc/cpuinfo | grep processor you can see how it iterates the processors detected from processor 0 and onwards.

I was already wondering if a VM could be setup to report 8 cores even though the host has less, sort of like virtual storage provisioning. But I'm not sure if 1: it is possible and 2: if Stanford would oppose that since they built in the rule of 8 or more cores. On the other hand I don't feel it is fair that a four core i7 is allowed to to run a bigadv unit (I'm know, comparing apples to oranges), but once again I'm not going to push their buttons when they built in this rule.
If I get the x6 I will be happy just running the A3's. Given the current Linux kernel issues with the GPU hack I need to dedicate a core to the GPU's. So I would be running -smp 5 anyway and force them on to cores 0-4 and force core 5 for the two GPU clients. If I can get even 10K PPD extra then I will be more than doubling my PPD output.
EDIT: BTW if any one is wondering how to set core affinity in Linux-
Code:
sudo apt-get install schedutils
taskset -c 1 place-command-here
