Computer building opinions

$400? You can get a Phenom II 1090 with 6 cores for less. The I7 950 may still be better though it depends on how the application utilises the cores.

Just get the best I7 you can afford.

With a good board the 1055T will OC just as well on air as a 1090T so might as well go for the cheaper option. X58 rigs are expensive to build, just look at the price of a decent board and RAM. For gaming the 950 is better, but the extra cost isn't really worth it unless you're going for a big budget build.

seriously though, is it possible to run 2 quad cores ?

You can buy motherboards that run 2x quad cores no problem. They also take a shit load of ram. However, once you're looking at that sort of hardware you're giving her the entire house in the divorce and you get the basket the dog sleeps in.

Keep in mind you can't run 2 Bloomfields or Gulftowns on the same board.

If you're giving the wife the house, grab some 8-core Xeon processors and ECC RAM. Server grade hardware will see ya right

Oops, Xeon MP X7560 processor is $6800 on pricespy though not available

I never knew you had met my wife

and the dog sleeps in a run outside ...I have a workshop with underfloor heating

so its all about the chip then , and floating point calculations

Here is what Open foam does

Don't suppose you know how multiple cores affect the application? Tried googling but all i found was a thread about someone wanting to upgrade their CPU to an i7 because their calculation took a week....

If you have a spare couple of grand to waste go nuts with i7 and lots of RAM. And an SSD of course!

Few consumer level apps can make full use of 6 cores. Most don't even make proper use of more than 2 cores. The exceptions are video encoding and CAD apps which will chew as many cores as you can feed them. Many of the newer games are designed to run on 4 cores.

I have to do a bit more research first but I think its the chip and ram that need to be man enough

Thanks all

Is the application GPU aware?

A quard core GPU will eat a quad core CPU on most mathematical operations performed on data sets.

Check out the CUDA standard.

The calculations I did used a course mesh, the finer the mesh ,,,,the more ommph you need and the better the results , me thinks

the lynfield chip is 20 000 yen , so quite affordable ( esp if I stop drinking ) and 2 x 4 gig of ram was 9000 yen

so 2 x lynfield chips and 2x2x4 gig of ram is 60 000 yen odd thats survivable ( a week or two of her not speaking to me ...kinda a christmas bonus )


Just a thought

no idea but will ask

Too much RAM can also be a bad thing. It's important to have a look at the latency as well. Cheap RAM can severely limit processor OC potential, especially with a locked multiplier.

If you're getting divorced anyway, do it in style and buy big iron. There'd be no house left to fight over

This may be a long shot but did you consider cloud computing?

Upload your data to the internet and let someone else's super ridiculously high spec'd machine do the work for you? Not completely sure but I gather you say "I want x no of cores at x speed for for x amount of time" and they just serve it up.


Alternately sift your way into NIWA, I bet their Cray would bang through your calculations pretty quick.
