Hello, this going to be my first time building my own computer and any help would be appreciated. I am looking to play lots of games like skyrim, far cry 3, ac3, sleeping dogs, gta iv, bioshock, etc and I was wondering if this build: http://ca.pcpartpicker.com/p/170Wn would be able to run all of these games at close to or at max settings 1080p. I would like to keep this under 800 so any suggestions to lower the price would be helpful. Also how long will this build last me? I already have a copy of windows 7 and a optical drive so those are not needed.
