Just received my base 27 with Fusion. Have not added any additional memory yet. First thing done (just for a test, I normally would not game on a desktop) was download Witcher 2. It was very choppy in native resolution on medium settings. Also the screen was not full screen for some reason- perhaps a driver issue? However, I dropped it down to 1080p (it looks fine at that resolution) and it runs smoothly full screen at Ultra settings. So I am pleasantly surprised that whilst not cutting edge, it still has enough horsepower to run demanding games at high quality settings, albeit at 1080p.
