# Ultimate CAD System for £3500?

Hi Guys,

Long time lurker, first time poster!

My boss wants me to spec up a new machine for running Catia V5, and Vericut Verification software. I know that an NVIDIA Quadro graphics card is a must, as is dual monitors, but what is the best CPU out there?

Do I go for quad core, or two dual cores? Also, what memory? And what sort of HDD?

I've been looking at the Dell Precision 490 and 690 machines, but I can't figure out what are the best options to spend the £3500 on.

He wants speeeeed. And lots of it, otherwise my P45 is in the post.

Thanks!

I have looked for this on the net and on all forums ppl who know their stuf not tards say it cant be done.

You can use the quadro drivers make windows call it fx 4600 or whatever but the performance isn't there.

Look at my 6800GT before and after modding

If top rendering performance is the criteria compare the Xeon 5160 3.0Ghz (dual core) and Xeon X5355 2.66Ghz (quad core) vs Opteron 2222 3.0Ghz. Generally the Xeon perform better in 3D rendering than Opteron and its especially true for applications that are SSE2 optimized. The Xeon X5355 is the more powerful rendering CPU. (I couldn't find out if Catia V5 and Vericut Verification are SSE2 (or higher) optimized.) http://www.anandtech.com/IT/showdoc.aspx?i=3057&p=12

The video/HHD/RAM choices you picked are fine. Stick with the Quadro FX 3500 video card.

I figured that if I was only running one or two really demanding applications, I'd max out one or two 2.6GHz cores, whereas if I had 4 3.0GHz cores, it might be faster?

Opteron Two Dualcore 2222SE vs. Two Dualcore Intel 5160 chips

WR2

August 7, 2007 8:03:33 PM

running SuSE Linux Enterprise Server 9 SP3

vs.

Two Dualcore Intel 5160 chips scored Peak SPECint_rate2006 54.9

http://www.spec.org/cpu2006/results/res2007q1/cpu2006-20070126-00311.html

It's OK to check the benchmarks like SPECint_rate2006 - as long as you understand it doesnt mean one CPU or the other will run YOUR programs faster or slower. And also remember most benchmarks run many different testing slices most of which have nothing to do with how your programs of interest actually run in the real world.

It's much better to find a similar type program and it's benchmarks. (from the link I posted earlier)

WR2

The 2222SE is a good CPU. The 3.0 GHz Opteron 2222SE can usually outpace Intel’s Xeon 5160 in three server-specific benchmarks (SPECint_rate_2006, SPECint_rate2006, SPECompM2001). If you were running a database server or web server the 2222SE would be the better choice.

The one benchmark that is of MOST interest to you is the SPECviewperf and its difficult to find heads up benchmarks. The Xeon SSE2 advantage is the reason the 5160 beats the even the Opteron 2224SE in the 3D rendering benchmarks above.

SPECviewperf offers users the ability to compare the performance of systems running in higher-quality graphics modes and using full-scene anti-aliasing. The product measures how effectively graphics subsystems scale when running multithreaded graphics content under the OpenGL application programming interface.

Current viewsets represent graphics functionality in 3ds Max, CATIA, EnSight, Maya, Pro/ENGINEER, SolidWorks, UGS NX and UGS Teamcenter Visualization Mockup.

You didn't mention what operating system you're considering but I'm guessing its WinXP Pro64?

Been thinking, and looking around everywhere, even at high spec gaming machines.

If I can do the soft-mod on the 8800gtx, and convert it to the Quadro 4600, would I be insane to buy an alienware Area-51 ALX, with watercooled, overclocked 3.33GHz Quad core processor? Is it even worth going for a high spec gaming machine, when I'll be doing high end CAD?

Thanks for all your help guys! WR2, you're a life saver!

and the Xeons use much higher cost FB-DIMMS and the MB have very few pci-e lanes.

Keeping in mind its not your own £3500 I'm not sure taking a gamble for a 8800GTX softmod is a good idea unless you can find lots of success stories from those who softmodded 8800GTXs in the CAD/CAM community. And get the boss to sign off on the gamble.

The AW 3.3Ghz QX6850 will have more computational muscle than the Xeon X5355 (2.66GHz) but less than a possible dual Xeon X5355 (8 cores). Unless your Catia V5 & Vericut Verification is optimized for SLI the extra 8800GTX won't provide any extra CPU processing speed. (Although it might be a bit easier to try an FX 4600 soft mod with a spare 8800GTX). If you wont need a CPU upgrade and the softmod 8800GTX turns out to be a viable option for you than the AW options isn't all that insane.

(1) If you use your programs mostly for heavy computational workload and average CAD/CAM display requirements it would give you more performance going with extra cores over a higher-end Quadro. (2) If your work product is average CAD/CAM computational workload and very graphics intense in display a higher-end Quadro starts to make more sense. (3) If its more of a balanced workload a balanced system works best with your budget.

Keeping in mind that my requirements fall in the 1st category here is what I'd choose for that £3500.

Dell Precision 690 Advanced workstation with Intel 5000 series motherboard. XP Pro 64bit

One Quad Core Xeon X5355 (2.66GHz,1333 MHz,2x4MB Cache) (future upgrade to 8 cores possible)

4GB DDR2 667 Quad Channel FBD Memory (4x1GB) and 2 300GB 10K hard drives (not using any RAID)

nVidia Quadro FX3500 Graphics Card

Dell UltraSharp™ 2407WFP 24" Wide LCD Monitor and Dell UltraSharp™ 2007WFP 20" Wide Monitor

and an upgraded ergo keyboard and mouse.

August 8, 2007 4:31:17 PM

Xeon 5355 2.66 GHz 1333 MHz FSB with 8MB Cache & Quad Core XP Pro 64bit

NVIDIA Quadro FX 4500 PCI-E 512MB DDR3

4GB DDR2 FBDIMM 667MHz - 4 x 1024MB

Single 250GB Serial ATA 3Gb/s Hard Drive

Two 19" Dell UltraSharp 1907FP LCD Monitor

for under £3,500

Ohhhhhhhhhhhh! Decisions-Decisions-Decisions!

If I was looking for the PC myself, I'd build it from scratch for £2500 and pocket the £1000, but since it's for work, it has to have a big fat warranty on it!

Got word from Catia and Vericut that their applications ARE NOT multi-thread apps, but that they can use the multi-threading on Windows XP to run the main application, and then batch programs (Not what I want). For example, I can be modelling, using one core, while another core is rendering another part.

Tempted by the soft-mod for the 8800, but I'm not sure it will work perfectly for the GTX card in particular. Haven't found any success stories for that card.

Didn't realise I could upgrade to 8 cores from that spec, so I think I'll go for something along those lines.
