A middle-range machine which can do (I hope) everything, with small compromises:
I won't play with super-high-details-with-AA for sure ^^
However I'm not a big gamer
The main reason of last upgrade (gpu), as it was too old (gt610 fanless, big mistake) for the octa-core. Usually, expect very new games, I use high, but when I play I do in windowed 1600x1200, which usually helps to make the things faster
