I have done as much research as is possible for someone with no computer background. I am currently buying this pre built system...

(sorry for the length of the link.)
To complete the system I am purchasing http://www.newegg.com/Product/Product.aspx?Item=N82E16817139021 and then a video card.
So my question(s) is this. Considering my budget (roughly 1200 USD) I can purchase either the gtx 560 ti-448 or gtx 570 for intel or the AMD HD7850.
I have researched enough (from my naive perspective) to know the cards, but I wanted to solicit this sites opinion for which card should I get.
Use is going to be for gaming of course, but it is MORE IMPORTANT to note, that I want a system I have to do minimal upgrades to for the next 5 - 8 years.
Any reply would be greatly appreciated.
