Your off by three orders of magnitude there. TH/s not GH/s.

His off what?
The way I interpreted the OP was different again: literally, what's the current BTC price (in say USD using MtGox) divided by the total hashrate of the network. And, what has this ratio been historically?
So right now (as I type), that'd be 41.56783/35.219 = 1.18 to 3sf. I imagine you could get historical data from bitcoincharts.com and crunch it yourself. Usual disclaimers about random fluctuations in both those figures...

I'm confused: are you asking
A) If you had 1TH/s of mining equipment, how many USD would you mine in 24 hours?
Or
B) How much would it cost (in USD) to buy enough mining hardware to reach 1TH/s?

Also, that doesn't include the motherboard, cpu, ram, cables, power supply, network cabling, routers, etc, to jam $305,000 worth of GPU's together.

Does anyone have a chart to show how much price per terahash has been historically, or what it is on average?
The most efficient GPU (in terms of Mhash/s/$) is the ATI HD 5830 which scores 3.28 (whereas a 6990 scores a 1.23).
The most efficient FPGA is the BFL single which scores a Mhash/s/$ of 1.64 (but provides better profit than a 5830 after considering the cost of electricity).
The most efficient ASIC is the Avalon ASIC which scores a Mhash/s/$ of 52.34. Followed behind that is the BFL Mini Rig SC at 50.16. The BFL rig might yield better than the Avalon ASIC as it is more efficient on a Mhash/s/J (power consumption), but electricity consumption is nowhere near the most important factor these days (... delivery dates are).
These numbers are from the Mining Hardware comparison article:

[Edit, Oops. fixed, added the K, thanks D&T.]
So a price of hardware per Thash/s would be the inverse I suppose,
GPU: $305K per Thash/s
FPGA: $609K per Thash/s
ASIC: $19K per Thash/s
