I need to build 2 more CAD rigs within the next week. I've been building X2 rigs, but with the release of core 2, I'm torn between the two. I'm going to post this in the Intel and AMD sections, because I honestly don't know what would perform the best for this type of application. These rigs will only been used with AutoCAD 2007 and MS office. I MUST have a Quadro FX1500 (599ish) and 2 gb of ram. We already have the monitors. My budget is $2000. So, AMD guys n gals, what should I build?

See my Intel rig suggestion here:
http://www.overclock.net/intel-gener...ml#post1349737

Replace the motherboard and CPU for these two:
MoBo: ASUS M2N32-SLI Deluxe Wireless Edition Socket AM2 $198.99
CPU: AMD Athlon 64 X2 4600+(65W) Windsor 2.4GHz 2 x 512KB L2 Cache Socket AM2 $269.00

Total $1,910.90 + $34.93 shipping = $1,945.83

General comment:
The Intel rig will be faster than the AMD rig by quite a margin. In most application the E6600 is on par with the FX-60 (both stock speeds), and the E6600 overclocks insanely (I get 3.5GHz on air with mine, at which speed it destroys anything AMD has to offer at this moment)

haha - core 2 is the way to go - i switched from my X2 3800+ oced to 2.6ghz (5000+)
in fact i downgraded my video card just because my 7900gtx wasnt a whole lot better than my 7800gt (at least in games, though 3dmark06 showed a difference of about 1500-1600pts)

basically core 2 runs faster, cooler, and is twice as overclockable. only weakness they have is with memory bandwidth but 99% of apps dont even need high memory bandwidth,

Yeah.. Core is the way to go, although CAD is the one thing where the difference is not as dramatic as in other applications.
http://www.digit-life.com/articles2/...duo-e6600.html

At stock speeds, the FX60 and FX62 beat the E6600. However, the E6700 beats them, so even with a mild OC, the E6600 will do so also. Again, since the E6600 overclocks like mad (3.5GHz on air should be no problem, even on my crappy motherboard), it will outperform anything AMD has to offer. The X2 4600 will be beaten easily, even at stock,.

The Core 2 Duo will still beat an Opteron, even in CAD. See that the Core 2 Duo even makes life for the FX series CPUs difficult.

And it depends which Opteron you choose. If yuo pick the 1xx series, then you can use socket 939 and regular DDR RAM; the 2xx series uses socket 940 and Registered /ECC DDR RAM (these two are thus older tech); the 12xx series are for AM2 with regular DDR2 RAM; and the 22xx series are for socket F and registered/ECC DDR2 RAM.

If you pick a server CPU with a server board, then Intel also has it's share of choices in core 2 duo Xeon CPUs, which again will beat the Opterons.

Actually, I was asking Space Cowboy if he needs to have ECC. I'm aware that certain Opterons require ECC and others don't.

If I had the money, Id probably go with a Xeon or dual Xeon configuration with a good workstation board

Thanks for all the input. I've decided to go with Chozart's recommendations, except for the case. I should be able to OC that setup 10% easily. Matching that up with the 2 perpendicular drives in raid 0 should make a hell of a CAD rig.

I hope you are going with the Core 2 Duo setup because of the extra L2Cache that you need for extra performance. That E6600 has 2x2MB of L2Cache and the 4600+ only has 2x512KB, which will create a huge performance decrease. Especially with a memory intensive application like CAD it will have to access your memory more often, thus slowing things down just a bit. I am an AMD fan, but for this application and comparable price I would go with the Core 2 Duo setup.
