Help buying an Alienware Aurora

[2NE1]

So I will be getting this Desktop early next year. Don't know a ton about PC's. Thanks to anyone that helps. Few questions I have:

1. With the options I have chosen will this be good enough for playing most games on the highest settings?
2. How many years of heavy gaming will I get out of this thing?
3. Should I get a better CPU option?
4. Is that a decent enough graphics card?
5. Is that upgraded sound card good? (For playing games and watching blu-rays with headphones) or should I stick with the original Integrated 7.1 Channel Audio option?

1. Onboard sound is fine
2. CPU is very good, especially for gaming
3. Consider a better Graphics card and/or SLI or Crossfire options

I guess then it would be future proof for atleast 3 years at HD resolutions

Can you indicate your budget, then better suggestions could be made.
