1) Bought a computer from tradingcomputers.com
2) It arrives and crashes...and crashes
3) They say they'll send me a replacement
4) 10 days later, said replacement arrives
5) Its specs are different. The original computer (the one I paid for) was an i7-based system running at 3.42 ghz. The replacement is an i5-based system running at 2.72 ghz. The windows score for the original is 5.5. The windows score for the replacement is 4.4.
6) I send the following email:

Just received today a replacement for the F-22 I purchased from you earlier this month.
The specs for this replacement computer are quite different (inferior), to the specs of the computer it is supposed to replace. Please see the attached screen shots.
Was my order confused with another? How do you propose to resolve this?
Look forward to your reply.

While your replacement F-22 might appear on the surface to be inferior to your original, your F-22 matches the configuration for our current F-22 model. They have decided to swap processors for better energy efficiency and stability. While the i5 might be a different family of processors, it is in no means inferior.
Regarding the CPU frequency, Windows System Properties often misreads the actual CPU frequency due to speed-stepping technology built into the processor. When your computer first boots up, the CPU is not under a demanding load, so it runs at it's default frequency (e.g 2.67GHz) to save energy. When the CPU begins to process more demanding data, the processor steps up the core frequency by adding additional multipliers that raise the actual CPU frequency to 3.71GHz as specified on your invoice. You will notice the original processor read 3.42GHz and not 3.71GHz. This is also a result of the speed stepping multiplier, but is not as dramatic on the more energy hungry i7 processor family. Unfortunately because the speed of the computer is dependent on the workload, Windows System Properties will never
show the maximum CPU speed. However, there are 3rd party utilities that can be installed to monitor real time system information.
If you're available Saturday morning, I can log into your system to
run a benchmark on your system to verify that is what is in fact
happening.
I understand it may be surprising to see such a large difference in
the same model of computer built only a few weeks or months apart, but this is a rapidly changing industry. I can ensure you that your current system will perform to the same processing potential of your original unit.

Ok, now, as I understand it, i7 is built for hyperthreading and i5 is not. As I understand it, that's a factor in running multiple (or individual) prorams, like Multicharts, designed to take advantage of hyperthreading.
But, really, I'm not a computer expert. I think this whole thing smells a little fishy, but I'm not entirely sure.
Anyone?
