HELP high end PC STORE US

[Falconex]

Hi , Im currently building a high end gaming pc , but in my country hardware is 10% to 15% more expensive, so im going to buy my hardware when I go to NYC.
What I want is a i7 haswell quadcore , and 2 gtx 780s, but I fear I will not find them on physical stores.
I just need names of stores on us so that I can try to search for them on google. Thank you
note:I already know microcenter and frey electronics (which they don't sell gpus)

Order parts online for delivery to where your staying before you go?

Just be careful, you may get stung on tax brigning them back.
