As a follow up and thanks for all informative posts, I would like to inform all (in the for what it's worth department) that I returned the HP computer to the dealer.
I now have an Alienware X51 with and Intel i7_3770 3.40 GHz processor, 8GB memory, and a Nvidia GeForce GTX 660 (1.5 GB memory).
The computer, so far, runs like a dream and I am really pleased with it.
You laugh because I'm different
I laugh because you're all the same
Of all the things I've lost, I miss my mind the most.
