Hi Keith,
Sorry for the bad news, been there done that a couple of times over the years.
Now this is just my personal opinion, I usually stay away from most company built computers. Some of them use special built motherboards, ram etc which make it harder to upgrade. HP is more known for their business computers than gaming computers.
I go with clone PC's built by well known computer shops that have been in business for years and have a good reputation.
Having said that Dell is known for good quality gaming computers if you want to go with a known manufacturer.
Cheers
