Updated Render Speeds With Different Hardware Configurations

Dell Precision T5400
CPU: Xeon E5430 (2.66 GHz quad core) (now x2)
Memory: 8 GB
Graphics Card: NVIDIA Quadro FX 3700
Hard Drive: WD Black 7200 RPM 1TB
OS: Win 7 Pro 64 bit SP1
Chief: X4
I have ordered another matched pair of CPUs in the same family (Matched Pair Intel Xeon 3.16/12/1333 SLANP Quad-Core Processor X5460), but are faster. I will let you know if that change affects rendering time. I'm also going to switch to a solid state drive (Mushkin Enhanced Chronos MKNSSDCR240GB 2.5" 240GB SATA III MLC Internal SSD) and will find out if that lowers the rendering time as well.
UPDATE
We have a few computers that started with the exact same specifications so it enables me to test different options fairly easily. Unexpectedly, changing to a high-end SSD drive from a 7200rpm optical drive did not change the rendering time in the single cpu machine (quad core). I then changed from the single Xeon E5430 (2.66 GHz quad core) to dual 3.16Ghz processors. The rendering time dropped to 1:06 from the original 2:31. On the computer that got dual 2.66Ghz processors, the speed was 1:16, so I'm assuming the 10 second speed increase was the change from 2.66 to 3.16Ghz processors.
In short, going from a single quad core processor to dual quad core processors is a great bang-for-the-buck change, going to SSD, not so much (exclusively talking about renderings here)...
I now need to update my specs in my signature line :-)
