intel core i7 $250 for a decently cheap one
$250 nvidia ($500 already)
$100 for a 1tb hdd + $120-150 for a 2tb external ($720-750 so far)
hd monitor depending on size if you're planning on getting atleast a 23" think $220 - 250
the motherboard will cost you around $100 - 200 ($1040 - 1200 now)
600w power supply $30 - 60

unless you already have a computer case and a dvd drive you're looking at another $100 to $200 on top of that so all together you might be into it around $1170 to $1460 sk8r4life
