Can someone customize this alienware desktop for me?

I am looking to buy a desktop for gaming and architecture related programming so i need good graphics. I have decided on this one desktop an Alienware Aurora. I know a good bit about computers but I dont trust myself in customizing my own computer i will use for the next 3 or 4 yrs. im trying to max it to where it will still be good for another 3 or 4 yrs. here is the customization website from dell. please customize it with optimum specs for under 1400 dollars. that is my budget. http://configure.us.dell.com/dellstore/config.aspx?c=us&cs=04&kc=6W300&l=en&oc=BA1SGA0&s=bsd thanks!
