I ordered the PC 3/4 months ago and was initially very happy because I switched from a MacBook and why PC gaming was just another great thing for me. However, I have to say in hindsight: if you want a real gamer's PC, has to reach much deeper into their pockets.
The GTX 650 is outdated. New games can be therefore just as playing on console level, which do not really make sense of the matter is if you have a PC buys (just the consoles cost half as). I am therefore now on the Gainward GTX 770 Phantom 4GB switched (the straight so still fits into the housing). Also, the RAM is probably not spacious enough for gaming, I would suggest a minimum of 16 GB here. Anyone who wants can also install a BluRay burner, be a nice thing.
What I did not notice a few months ago: The power supply is the largest scrap. I'm here love to switched to a modern and quieter Corsair power supply, since one with 500W also can not really upgrade. The motherboard is relatively tidy for the size, even if I only have one more with built-in video card PCI port free.
