Hi guys,

Now I want to build a computer for intensive calculation. I am expecting to spend somewhere 4000 dollars just for machine. The only thing I must need is nvidia video card. hhd size isnt important but the speed is. Do you guys have any suggestion?

Very interesting link. However I am a mathematician not a computer builder. I do find building computer entertaining but I looking for something practical and ready to be used for numerical programming.

Yes, with $4000, you should be able to build something nice. With that kind of money, you should probably look at an ASUS board with dual Opteron or Xeon processors. That will give you eight processor cores. Then, you should load it up with eight GB of DDR 2 RAM and one or two Nvidia cards. Buy a 1000-1500 watt power supply. Also, you should probably have money left over to make a five or six hard drive RAID 5 array. Be sure to buy a UPS. For about$4000 you can build a very powerful computer, as I mentioned, capable of driving four monitors (which can be used for CUDA if necessary), with eight processor cores.

And, as an added bonus, you could choose to run 64 Bit XP, Vista, or 2008, or most Unix systems, so it should be good for whatever kind of software and operating system you need the workstation for.

Your other option, if it is suitable and you have the technical expertise, is to buy some used computers, install Linux on them, and run a Beowulf cluster, which might be more cost efficient than a single computer, and would not require a graphics card.

Why nVidia?

Does your application benefit from parallelism?

Nvidia does currently have more perks when it comes to incorporating the GPU for computational power...

I am going to write apps with CUDA. This is the whole idea

Get a big case, a 1500 watt power supply (try ultra), and a motherboard with 4 PCI express x16 slots, and throw in four Nvidia cards (or start out with two, and then add the others when they come down in price).
