computer rig

i plan to buid a new computer here is my rig
Lian Li Lancool DragonLord K58 1 58,89 € Corsair TX - 750W 1 115,95 € Intel® Core™ i7 975 Extreme Edition - DESTOCKAGE 1 839,99 € MSI X58 Pro-E 1 159,99 € Corsair Dominator 3 x 2 Go DDR3 PC12800 CAS 7 2 519,97 € Cooler Master Hyper 212 Plus+ gts250 1gb
vevociraptor 150 g 7200t/mn

It will be around 1700 €
in the other hand i got the possibility to buy a mac pro 8 core for 1200 euros (the happertown model)
I would really appreciate your help and concern.
what do you think

Add a new graphics card and a ssd disc for the mac and then install win 7 through boot camp.

8 core is better than 4.

First, it´s Harpertown, not happertown.

The i7 975 is a complete waste of money. You need a single processor with that much power if you plan to buy 10 of those machines and need each to perform at its peak and in a cluster.

If you think of getting it for lightspeed rendering, then you can buy 2 quadcore machines for the money the processor costs. Take the i5-750, it comes with 2.67GHz reference clock and it takes 10 seconds to set it to run with 3.6GHz on Aircooling rockstable.
The i5 will not perform as good though as it lacks L3 cache and SMT but they´ll make quality up with quantity.
If you switch to AMDx4 or x6 you get even more power for the same money - for blunt render force.

Performance to cost is not a linear graph and there is a point where it gets uneconomical.
30% more performance for 10% more cost?
5% more preformance for 50% more cost?
2% more performance for 80% more cost?

It is for you to decide where economical ends…

And compared to the i7 975, the GTS250 is in no relation.
It is like buying a trailer coupling for a ferrari.
If nvidia and budget I currently recommend the GTX460 with 1024MiB Memory (NOT the 768MiB!)
Then again, it is a matter of what you exactly want to do with your machine.

Always keep in mind as well, nowadays Intel processors got no fixed speed.
The got a VTT at wich the processor runs 100% stable with the reference clock.
It is a recommendation by Intel, not a rule. As long as you stay below the maximum core voltage OC’ing doesn´t even void warranty.
My CPU has a VTT of 1.225V. It runs 30% OC´d with 1.248V. Maximum is 1.375V specced by Intel.
The C2D, C2Q, Ci7 and Ci5 series can be overclocked like hell without any major geek knowledge, so its not always the best to pay double the price for a processor that is 200MHz faster…

Ok, thanks you. I will not spent all my money into an i7 975. But what would you choose a new i7 or octo core mac pro (2008)?

Counterquestion: What tasks are you going to perform with your computer?

Rendering with reflections and raytraced AO and stuff?
Stills or Animations?
GPU Rendering.
DTP Posters with huge resolutions or HD content?
Lots of particles and physic?
Using Adobe Suite, or Autodesk programs?
Single or multiple monitor workplace?

You can always buy pants, the question is you want them to cover your ass or you want them to fit perfectly? :smiley:

However, for what i get the max pro got dual quadcore xeons in it. you can always utilize that and install windows like BB said, or linux, or go along with mac os if you want. with that machine you got all options if you can upgrade hdd/graphicscard.
Upgrading ram would be expensive though, dual processor boards require ECC registered memory modules… $$$
On the other hand it is the question if something else used or new would be cheaper, mac´s are not actually known to have a good price/performance ratio, nor to be a bargain buying used.

96 GHz renderpower in a box RTR anyone? :smiley:

I plan on buying a new pc that has equivalent 975, but OC’s a 930 to 4.3GHz. specs below. From TigerDirect for under $1900. 4T Raid at 12Gbs, 2T backup, switch is needed for dual monitors. comments?

Yes, next time paste without html tags :wink:

I don´t get why you need the switch for dual monitors?
If you can spare the hybrid SLI with the onboard graphics, you can plug your mainscreen in the 9800GT in single display performance mode for full 3d acceleration, and plug the second screen in the onboard card for tutorials, browser, reference pics, or application toolboxes.

If you want to use the hybrid SLI to power down the 9800GT in 2D mode, you might get performance issues having 2 screens on one card if you intend to use 3D on both screens.
I got 2 cards, one for each screen running in single screen performance mode so i got full 3D acceleration on each screen.

And I wouldn´t get the H50. It barely outperforms an aircooled tower cooler like the scythe mugen, noctua uh12 or uh14 or prolimatech megahalems.
The new H70 performs slightly better, but as all in one watercooling it lacks performance, and the pump is said to make very annoying sounds. Rather get a dedicated watercooling with a nice 3*140mm radiator and maybe an eheim pump. You also got the modularity to put the graphicscard or chipset or memory in the cooling circiut then.

The 1050W PSU might be overkill, but if you plan to OC the processor and want to have reserves for a HD5XXX/GF100 lateron it should be a good choise. Personally I recommend Corsair PSUs. Bargains, high efficiency, 5 years warranty and strong 12V rails - which is important if you OC.

The OCZ memory got nice OC capability as well, just make sure you got enough reserves. I don´t know for the X58 chipset but X48 and below, only nvidia chipsets are able to unlink FSB:DRAM. For all other chipsets the memory clock always is a multiple of the FSB.

The system overall seems to be sound. If you plan to play, the Graphicscard does not match the processor. Then you should get a GTX460 or higher or a HD5830 or higher.
