Thats a pretty general question. There r so many options for a gamming pc ranging from $700-$3000. Its hard to say what is best for ur price range. My suggestion is to get an xbox360. They r $100-$400 depending if u want new or used. They dont glitch or lag if the game is to "big" for the processer. All Games run awsome. There is nothing more anoying than getting a new game and ur pc is just a tiny bit to slow to support the game properly. Then u got to go out and spend hundreds of dollars(pounds, lol) just to make it work. Sorry for my opinion thats kind of off subject, but i encountered this problem so many times. I put probably $3000 into my pc over 6 years just to keep up with the gamming industry standerds. I baught my xbox 4 years ago and havent put a dime into it. Plus if u prefer a mouse and keyboard for gamming, xbox360 supports that too.
