I have Two GIGABYTE HD 5870's in CF and a Corsair TX850 850W power supply. Is 850 enough for these GPU's? The rest of my system includes a Core i7 930, 6GB DDR3 RAM, X58 motherboard, and a 2TB HDD.

Should I have gotten a 1KW PSU?

You have plenty of power. 850TX has a 70 amp 12 volt rail. Pair of 5870's will pull around 25 - 30 amps under load. CPU, about 10 amps. That leaves plenty of power for the rest of the system plus a healthy reserve.
