Why hello there everyone,

I just started mining today with two computers. One has a GTX 570 and the other a 560TI.

Now I read here that the Nvidia cards dont do so well which is a shame but still I would like to know what I can do to maximize my performance.

I currently use GUIMiner to mine and with my two computers my combined mine rate is something like 200 MHash/s

Is their any flags I can add to increase this? My 560TI runs 24/7 while my GTX runs about 18 hours a day (the other time I use that PC for graphics rendering and gaming etc). What can I do to maximize my mining?

Im running slush's pool currently and have both of my my GPU's set up as different miners (I think this is what I should be doing?).

At this rate is it even worth mining? What other avenues for coin generation can I pursue?

Thanks

Other avenues for coin generation?
Invest into an FPGA miner - that's the only way to be future-proof today.

Two machines each armed with a single nVidia card is a truly horrible set up, to the point of being laughable as anyone's idea of a mining rig.
You're burning up much more money than you'll ever earn unless the exchange rate skyrockets to $30, which isn't exactly the most likely of scenarios.

Don't mine on slush, the damned pool is not only hoppable but it's been exploited for a very long time.
Find yourself a nice zero fee DGM or PPLNS pool and mine there. I've been very happy with BitMinter, Ozcoin and Eclipse. Those pools are rock solid.

Get some AMD 5850s or a FPGA miners. Abcpool seems like a good pool with no fees

I have a 5750 thats lying around I could use. But I would need to build another pc to house it. If that is running 24/7 what do you think would be the bitcoin rate on avg?

A highly overclocked 6750 (basically the same card as your 5750) can pull 206 MHash/s.
This low-end card can do a better job at mining than two of your nVidia cards put together and at a fraction of the overall power usage.

Why build another PC? Either put the two nVidia cards together or simply sell the 560Ti.

I use my 570 PC for gaming purposes (just built it) and video editing for my job. The other PC is my in-office comp which I use to test out games to review (I work for a game review website). I cant swap anything out of my work pc (with the 560ti) and I wouldnt want to swap out my 570 just to mine since the 570 does really well in other fields I use it for.

Thought about getting a 7970?

Ah I wish but I just invested in the 570 and now I must invest in things like an engagement ring Tongue

Having one card per rig and horribly inefficient cards at that is a good way to waste a massive amount of electricity for a tiny amount of coins. 

I use 3x5970s (6 GPUs) rigs w/ an underclocked sempron and usb drive as the "hard drive" to mininize the host power because the host nets you nothing.  I am moving them to 4x5970s rigs to make them even more efficient.

I know it sounds harsh but mining the way you are is a good way to turn something into nothing.

With your current set-up you'd best forget about mining.
By the end of the year you might need to pay the equivalent of that engagement ring in power costs if you proceed with the nVidia cards.

Re: electricity consumption. Consider mining seasonally, e.g.: only in winter when the heat can offset pre-existing heating costs. Otherwise, remember that air conditioning has to work harder to extract unwanted heat.
