GPU Validate Error on new computer, Help!

(moderation:
I have just built a new gaming computer for a client and installed Boinc last night.
However, this morning when I had a look at the tasks I noticed a lot of 'Validate Error' (45 and climbing). What is wrong?
The system config: i7-3820, 16GB DDR3 @1600MHz, Galaxy GTX 670, Antec 750 watt Games PSU, Win 7 64-bit pro, Intel 335 180GB SSD.
The CPU is O/C with multiplier 43 to run at 4.3GHz and there are no stability issues and errors on CPU tasks.
GPU is running at 66-72 degrees C, power is at 80%, and GPU usage around 85%.
I am running 3 tasks on the GPU, the same as my other computers
Here is the computer:

Is the GPU overclocked?

I had it over clocked like my other Galaxy GTX 670 GPU's to about + 45MHz and about 120MHz on the RAM.
I have now brought these down to 0.
However, GPU temps, power and usage are all fine.
I will see if down-clocking does anything, but it was just a small O/C and the same as the other three Galaxy GTX 670 cards.

Each CPU and GPU is not the same. 2 GPU cards same brand both being geforce 650 will not clock the same.

Yes that is true. However, I don't get a computer error while processing the work unit but only after it is completed and uploaded.
If it was iffy I would have expected errors during the computer, like SETI does, and not complete the WU and then say it is invalid or is that the server that says that?

It depends on what went wrong... if there is a data error then if there is a 3 when it should be a 4, its still a valid numeric answer and then the only way to know that something went wrong is through the valitation against other rasults from other users... if there is a letter intead of a number then as the hardware doesnt know what is expected there it also sends the result as if it were ok, this kind of errors are detected on the server without needing a comparison with other results...
Now if the error is in the executable data then the app will fail while is beeing crunched and BOINC will stop it marking them as "computation error" and report it back without sending any result.
(Take this as an idea of what happens, its not exactly as Ive said)
I have a GPU that Ive needed to downclock their memory due to 1/3 of the tasks beeing marked as invalids... just 20Mhs less than their default speed fixed it even when the GPU cores are overclocked wildly...
