What computer for SU?

That makes sense Jeff. It still seems a bit of a waste of resources though.
It's a case of 'the more cores the better' with CPU rendering, so I don't think it's unreasonable for programmes like Sketchup to also make use of that computational power.

it is sort of unreasonable though.. when the GHz race stopped and the multicore race began, lots of people didn't even blink an eye and just started buying more cores instead.. in many situations, doing more harm than good and spending too much on resources that will sit idle.. relatively speaking, very few processes can be run in parallel (talking about all apps even.. not just CAD apps.)
coders used to rely on hardware to speed up their inefficient code.. the hardware is sort of at a standstill now so it's up to the developers to rewrite/refine their algorithms so they'll run faster.. or accomplish the same thing with less steps.. some programs do this better than others and when we compare apps, we can sense that sketchup has some not-so-smooth algorithms in place which is why it bogs down quicker than other programs.
but if you can come up with the algorithms to allow naturally linear processes to run in parallel then you'll pretty much be an instant millionaire and instant hero.. it's not as if there aren't major incentives to figure out how to do it.. you also have to realize some of the smartest people in the world are trying to figure it out and can't. so in that regard, it is sort of unreasonable to expect sketchup to run most of it's operations on multiple cores.

When you put it like that, it does sound unreasonable. I suppose we just need to wait for some genius to make a breakthrough that will revolutionise the way that software can utilise the advances made in hardware development.
In the mean time I suppose we'll just have to hope that chip speeds start to increase again.

heh, yeah.. but we can't let the developers off so easily
sketchup was written during the ghz race so a lot of the code was "we'll just write it like this for now and speed will double every year or so with hardware advancements.".. but it only worked out that way for a handful of years then tapered off.
a lot (most?) of that code is still in there as the back bone of sketchup. if the developers were to convert to 64bit, they'd be rewriting this legacy code and it should present an opportunity to not only update the program to 64bit but, maybe more importantly, throw out some of this GHz-race based algorithms and write smarter/more efficient code with the mindset that 4Ghz is basically max clock speed.. it's a big undertaking to convert to 64bit.. it's much more challenging to redo the algorithms. if they simply kept everything the same but made it 64bit then that's sort of a waste.. if they redo the way sketchup fundamentally works under the hood, then it's not a waste..(disclaimer- lots of speculations made in this post
) -
I have to wonder whether some of the resistance to 64 bit is really motivated by a preciousness towards the original code and a desire to avoid the complexities and consequences of rewriting outdated algorithms.

Numerobis,
The Xeon model I've gone with is only 2.8GHz and my current chip is an 3.2GHz i7. Not much of a difference, but enough to concern me.
If your Xeon 2,8GHz is something like the E5-2680V2 you have 3,6GHz single core turbo, so no, there is almost no difference to your 3,2GHz i7 if it is a 3930K with 3,8GHz single core turbo, since the E5 V2 is Ivy Bridge based and a few percent faster at the same clockspeed. If we're talking about a old i7-9xx 3,2Ghz (960/965) then your xeon should be clearly faster.
-
Yep, I'm going with the E5-2680V2....they seem to be rare as hen's teeth & my builder has had to order them from the States.
My current chip is an i7 960, which runs at 3.46 GHz with Turbo (probably slower the way it's been performing recently), so the Xeons will certainly be faster.
Thanks for the help & reassurance. Time to breath out a long sigh of relief and crack open the first beer of the weekend.

if it's not too late and you can scrape together another $250 or so, get the top end 8core instead.. that's the one-- especially for a modeling/render combo chip.
.
that aside, some people are already modding the new mac pro with the 10-core e5v2.. pretty sweet

The 2680 comes In 8 or 10 core flavours and I've gone for the 10 core version.

the 2667-- 8core 3.3ghz with turbo to 4.0.
it's the best of the e5v2 xeons (imo)(fwiw- these are all outside of my spending limits.. I'm getting a 1650 (6core).. it's a lot easier for me to tell somebody else what to buy since it's not my money I'm spending

Unfortunately the chips are already on their way from the US, so it's really too late to change my mind. Thanks for the advice though.

Wait till you hear what Hieru is paying in Vat taxes... Sheesh. He's getting robbed coming and going.

Luckily I managed to get a much better deal with someone local (plus custom water cooling). Now I'm only paying cost for parts, plus labour; which means that I'm spending what I thought I should before I received the ludicrous quotes you're talking about Kristoff.
-
That's good news Hieru... Money should be going where it belongs... SPEEED!

....and beer
Seriously though, if I had 10k to drop on a PC I'd have gone for a proper bespoke job with someone like E22.
