Hi

I'm in the market for a new computer to run heavy-duty eulerian and langrian model simulations with more than 15.000 individual calculation cells and 20.000 timesteps.

My budget is roughly 2000AUS$ or 1700US$

Graphics and gaming perfomance is secondary for me, what I need is raw and fast calculation power. Unfortunately I have a very limited knowledge in building computers so I would be very grateful if you guys could help me out with a powerful build within the range of my budget.

So far this is the build I've come up with:

  • CPU: INTEL Core i7 920
  • Motherboard: MSI X58 PRO-E, DDR3 MB with 6 x DIMM, Max 24G of Memory and DrMOS Technology
  • RAM: 6(3x2)GB Corsair XMS3 DDR3 1600MHz ram Low-Latency, run in Triple Channel Configuration with Heatspreader and lifetime warranty
  • Hard Disk: Seagate 1TB SATA II 32M cache
  • DVD burner: Pioneer DVR217BK 20X Dual-Layer SATA Burner (or LG 22X SATA Burner)
  • Video Card: MSI (or Palit, Galaxy, Zotac) Nvidia GTS250 1G DDR3 Video Card
  • Network: Gigabit Ethernet on Board (Broadband Ready)
  • Sound: Home Theater Quality 8 Channel High Definition Audio on Board
  • Case: Antec Three Hundred Gaming Case
  • Power Supply: Codegen (or Titan) 600W Dual 12V Power Supply
  • Warranty: 1 Year RTB Warranty include parts, labor and test service /

    PRICE: 1616,00 AUS$ / 1341,00 US$

Now this is a bit under the budget, and I'm in doubt if I should use the remaining funds to upgrade to a core i7 950, or increase the memory, or perhaps buy an effective cooling system so I can overclock my machine while I run my model simulations?

All input is welcome: both to the current build and the upgrade ideas! I hope to hear a lot of feedback from all of you.

Cheers!

Hi and welcome :)

Where are you - AUS or US? This will make quite a difference as the market prices are not equal. Also where are you buying from?

Cheers

Hi, and thanks for the warm welcome! :)

Im located in Australia and will be buying from an Australian supplier. So far I've found the best offers on pre-build computers from this ebay seller:

Two points about your list first: 1) No OS listed 2) Get the PSU upgraded from the cheapo Codegen to something decent.

Thanks for your reply :)

OS is not included in the price from this seller, but I have a copy of vista home 64bit which I intend to use unless I can get some kind of sweet deal on windows 7.

What do you recommend instead of Codegen? I can get a Asus 750W Power Supply for around 211 aus$ at www.getprice.com.au, but I honestly have little to no knowledge in difference between PSU's, and I'm currently a bit too busy with my MPhil to do proper research in the various PSU's out there.

I just noticed that you're located at the Gold Coast, so I was wondering if you could give me some hints on where you normally buy computers/parts from? Im located at the Gold Coast as well you see :)

For a build like that, I would be looking at using either an Antec, Corsair, Seasonic, or OCZ power supplies. I use whatever's the cheapest from my suppliers when I need it - all those brands are pretty good. Somewhere around the 500-600W range would be sufficient.

I'd go 650-700 just to be on the safe side.

That's not necessary. A high-quality 400W PSU could easily power this build.

Thanks for the input guys.

I've made some changes to the original build-idea: I added more RAM and found a low-noise case and PSU, which can support RAID once I can afford additional harddrives. Graphics is as mentioned secondary which is reflected in the budget choice of a Sapphire 4670.

Intel Core i7 920 2.66GHz LGA1366 CPU
ASUS P6T X58 Motherboard
12GB G.Skill RAM (2x 3x 2GB) DDR3
Harddrive: 1TB Seagate 7200rpm SATA Hard Drive
Samsung SATA DVD Burner
Sapphire 4670 Graphics Card PCI-Express
Corsair TX-650 650W PSU
Antec P183 Black Case
