Joe,
I have always tried to go for over kill also. I got the best graphics boards and processors. Now I am using an old Gateway that I had custom built almost 8 years ago and have gone through two hard drives and a CD/WR drive on it and it still is far superior to what they build now. I would not buy another from them as they have did away with the build your own since selling out to Acer I think it is and the drive trays I saw in their top of the line one were so flimsy I would be afraid to put a disk in them for fear they would break off. I am far past the point of needing a lot of power any more and these older ones do just fine so I will stay with them for as long as I last.
