oh, you can get a decent update for less than 1000, especially if you already have a 1680x1050 monitor.
I'll even throw in a new Power supply:
Note you'l have to wait for the end of the month for this, and I'm assuming you are in the USA.
Intel i5-2500K: $225
AS Rock Extreme 4: $152
DVD burner: $18
8 GB DDR3-1333: $80
HD 6850: $180
Samsung 1 TB HDD: $65
SeaSonic 520W 80+ Bronze: $70
Rosewill Destroyer case: $50
$840 total, and the PSU could handle a second 6850. If you add a second 6850 it becomes $1020
