What "speed" should I be mining bitcoins? It seems slow. What am I doing wrong

[Shadow Wizard]

I have just started with bitcoins and bitcoin mining.  I have set up GUI miner on 2 systems, one with dual GeForce 9600's and one with a GeForce 350m  I have both machines connected to deepbit, and running CUDA miners.  I am getting about 14-15 Mhash/s.  But I have seen screenshots of people getting 10X that.  Is my machine really that "Crapy" for mining?  Or are there some settings that need to be adjusted, and what are they?

NVIDIA, forget it, you need ATI theres no point otherwise....

That sounds about right. take a look - https://en.bitcoin.it/wiki/Mining_hardware_comparison Nvidia is just worth the the power used to mine at the current difficulty,

what's the average speed that people can mine bitcoins?

Nvidia isnt great for mining really.

however, if you upgrade your drivers to the latest version, install GUIMiner and have it set up a CUDA miner, you might get an improvement.

You are using Nvidia, they don't mine very well

You should get ATI cards to have good speeds

There is no average.  It all depends on the cards you're using.

My personal average is 308 Mhash/sec/card.  I'm using ATI 5830s.

Thanks.  Will even help me is deciding on a new video card.
God I hate ATI

How much do you want to spend?
Dollar for dollar the best cards I can think of that come to mind...
Hd 5770: less than $100. Generates 200mh/s easily enough.
hd 5830: Between 100 and 200. Generates 300mh/s or more.
Hd 5870: If purchased for less than $200. Generates 360+ mh/s.
The hd 6950's are around 200 dollars after rebates from XFX, those put out about the same hashes at 5830's

Now, if like me, you find a 5850 or 5870 for less than 200, pick it up asap.

You should overclock them all. Even a bit. It gets you more for your money.

I am glad you asked.  Been looking for one.  The issue is I can only take a single width card.  So the question is, what can I get in single width, that will give me 150+, for under $150?
Oh yes, it also has to be a current production card.

Don't you have the mandatory fifty-three Radeon GPUs, water-cooled in an open case, with the fourteen 5.6 Ghz Core I7?
And don't you have to balance it all on your boobs/moobs?

Why can you only take single-width?  Just buy a PCI-E extender cable and mount the card somewhere else in the case.

If you're going to force single-width, then just keep mining on nVidia.  The double width cards are double-width because the heat generated by the GPU(s) requires additional cooling that a single-width card cannot accommodate.  So the only single-width cards you're going to get are going to perform as poorly as your nVidia.

Better yet, just don't bother mining.  You'd be better off taking your $150 and buying 10 BTC immediately at the exchange.  It would take you months and months of mining on a single-width card to generate 10 BTC (probably closer to a year).  Then wait for the price to go to $30 again, sell them, and then buy a nice rig.
