hey We can help you set up your rig with that budget you can easily get a similar spec PC with a 780 6gb (if you wait a couple of weeks).
BTW I build and shipped a PC with 32 gb of ram a 780 ti, i7 processor with liquid cool (H60) for approx $2200 this is counting shipping to him ($80) and my "tech charge" he could not buy from cyberpower or anything since he lived in non us 48. so rate was considered international.
also cyber power have way better deals than those :

(replace card with 780 ti EVGA super clock ( no price difference) . So for the same price you get a 780 ti instead of a 770, better cooling, and probably better warranty (cant tell tho)

Do you have access to accepting deliveries via USPS, UPS, FedX, etc. or would you be better off buying parts retail? Do the names Microcenter, Fry's Electronics, NewEgg, TigerDirect, have any familiarity?
These are some of the better places to shop (selection, competitive pricing, warranty/return policies) that most folks around here use. And there are other good ones. Just getting some ground work done......
Amazon has became one of my top places to buy now. they also carry mail in rebates in some cases.
