Yes Pc gaming may be better graphics and frame rate.
But not many people have 5k plus to spend on a super computer.
Also at the rate graphics cards are released and the best being 1k plus
it terrible.
Also the fact that you can sit at the compfort of your couch playing games , i would rather sacrifice a little graphic difference.
Again, some of you have no clue as to what your talking about. I only spent $1500 on mine almost 2 years ago. And its a very powerful system compared an Xbox. It plays everything on full settings flawlessly. And it's a generation old system, X58 chipset. And I didnt even need to spend the $500 that spent. I could have went with a smaller display (22") and stock cooler and my system would have been around $1000. I have 660ti graphics card in mine and it is a beast. You don't need a 690 graphics card to play games. That is really meant for game designers, not gamers. Lol.
You could get one 660 now and then get another one later and run the two of them SLI if your playing more advanced games down the road.I plan to jump to Haswell when it is released.
