Regardless of the Nvidia debate, the question still stands...
Is there a way to change/adjust GPU "usage/or intensity" and/or target temp? Ideally via a parameter to cudaminer?

No, it doesn't depend on future prices at all, it's because Nvidia cards have absolutely atrocious hashing speeds: https://litecoin.info/Mining_hardware_comparison#NVIDIA . This is why I said you'd pay more in power than what you'd get back. The list has a total of five Nvidia cards that are benchmarked at over 300KH/s; actually, it's 4 cards but one is listed twice with different cudaMiner arguments. For the average price of a GTX770 ($350USD according to newegg), you can get a Radeon 7950 that easily does three times the hashes per second.
Using a calculator with your hashes, a modest 1% pool fee, hardware cost of $350, a (very low) difficulty increase of 5%, you'll literally be losing money: https://www.dropbox.com/s/rk4alkioi9mmsxg/shot_131212_021121.png (generated using http://bitcoinwisdom.com/litecoin/calculator). As you can see, in 119 days, the difficulty on Litecoin would be high enough to be that you'd literally never generate income with a new GTX770. Conversely, using the exact same data but clicking on "Radeon HD 7950" at the top starts generating income in 77 days and you actually continue to make money.
So think my reply is false all you want, the published data says otherwise.

Well that really depends on FUTURE prices now doesn't it? I think it is safe to say anyone mining altcoin/cryptocoin is "speculating" at this point. I believe in the "fullness of time" your argument will be false. But anyhow thanks for your helpful and throughtful reply.
One way I just did to decrease temps was to us MSI Afterburner to decrease max power limt which seems to working nicely bring temp down to 60. Of course rate has dropped to around 195 from 220 but I am fine with that. How does this solution sound to people?

hey folks! Well I have been mining on another rig using 6770x2 and cgminer with good results. I have a GTX 770 on this one so I though I would give it a go to see what get. Using simple launch config with autotune getting 230-240 Kh/s with not bad considering I guess BUT the TEMP goes up to around 69/70. This may not seem that high to some but this is primarily my gaming rig and don't want to shorten the life of my GPU to much. Is there any commands/tricks to "decrease" GPU usage to keep temps down alittle. I tried setting to lower priority without success. Also is there a way to undervolt, which in turn may decrease temps/increase life.
Cheers!

Yes, just don't bother mining with an Nvidia card, problem solved. You're going to spend more in power than you'd make in mining.
