Any Processor Tests? Benchmarks?

[immortal26]

Before I buy any new servers which will mainly use ImageMagick, is there any benchmarking tests on duo and quad-core systems?
I know IM can use both, but I just want to make sure if it's worth it to go for a quad-core or if a duo would be good enough.

The system may require 100's of process's hitting ImageMagick a minute.

RAM will be 4gb.
Looking between:
Intel Core 2 Quad - 2.83 GHz
or
Intel Core 2 Duo - 2.13 GHz

Don't want to pay to much if I don't have to, but if I have to I will fork it up.

We put together a quad-core box with a 300GB Sata drive and 6GB of memory for $1700 USD from NewEgg. Since ImageMagick algorithms are threaded, we recommend 4 cores.

Thanks Magick, that's all i needed to know.
Also, that's a great price... Can you pass a link to the processor you used?

Intel(R) Core(TM) i7 CPU 950 @ 3.07GHz.

Note that with linix a i7 processor produces 8 threads and thus linux treats it as 8 CPU.

Makes it very fast, at least for most operations.
