Hello all,

I am planning to assemble a system which should work perfectly per my requirements.
I need a system for 3D CAD applications CATIA V5 and UNIGRAPHIX.
In my company there are dell work stations with Xeon T5500. Which are very costly.

I am confused with i7, Xeon and AMD FX processors, which would serve.
My application with these CAD tools will be very heavy and complex assemblies.
Also planning to buy 1 or 2 tb nvdia and 16 or 24 GB ram.

Please guide me on the same.
Thanks

Sarthak

Look at the Xeon E3 series. They're basically slightly lower clocked, multiplier locked i7s. You get the 4C/8T support and higher L3 cache that will benefit CAD. As a Xeon they even support ECC RAM, and some even come with an iGPU if you want. And you can get them for just a hair more than an i5.

The FX will give you eight true integer cores instead of hyper-threading, but their poorer IPC means they have to be overclocked just to match an i7/Xeon, and they put out a lot more heat doing it. But if you want to save money and OCing is okay with you, they're not a bad way to go.

I completely agree with your suggestions I just wanted to interject slightly and state that FX is not all that hot even overclocked. FX CPU's max core temp is only 62c, with a stock cooler at stock clocks they will get close to that under full load. With an aftermarket cooler and a good overclock 4.5+ they will hit roughly the same temps, lower with a lucky chip. All the same its not uncommon for 3rd/4th gen core chips to hit 75/80c quite easily under prolonged load with the stock cooler. However for the users needs I agree with the E3 at stock clocks and a decent air cooler just to keep the temps in check.

Oh, and in case the OP didn't know, the Xeon E3 all fit in desktop sockets. The v1 and v2 are SB and IB respectively and fit in 1155, the v3 is Haswell and fits in 1150.
