<p>The general answer is that your card replacement caused the huge drop in hash-rate. Radeon cards are generally better for mining (faster and more efficient) compared to Nvidia. There is a nice chart that approximates hash rate per card here: <a href="https://litecoin.info/Mining_hardware_comparison" rel="nofollow">https://litecoin.info/Mining_hardware_comparison</a></p>

<p>You should really consider mining scrypt algorithm at either a profitability pool (I think BTCGuild has one now) that will mine the most profitable coin and convert it to BTC for you, for a small fee of course. This should increase your mining yield by 10fold or so!</p>

<p>You also might try Cudaminer instead of GUIMiner for nvidia cards. I have had better using cudaminer for nvidia gpus than both cg and bfgminer.</p>

<p>you need to be using the cudaminer for Nvidia..</p>

<p>and now you should be using x11 to hash..</p>

<p>my GTX650ti went from 200kh scrypt to 1100kh x11 coins..</p>

<p>hit up a multipool like blackcoin.co/mining/ </p>

<p>check out <a href="http://www.blackcoin.co/" rel="nofollow">http://www.blackcoin.co/</a>.. </p>

<p>that card should scream.. especially with those specs.. maybe 2.4 to 3.4MH</p>

<p>I make 12 BC a day @ about .00024 Btc each a day..</p>

Please use proper sentences and don't overuse abbreviations that uninitiated won't understand. The answer seems to be spending a bigger portion on a tangent than on the actual question. It would be beneficial if an explanation were given why the asker should be using Cudaminer.

<p>I am a gamer who simply uses his rig to mine when idle. A year ago I was getting 0.5 Ghs using a <a href="http://www.sapphiretech.com/presentation/product/product_index.aspx?pid=1463&amp;lid=1" rel="nofollow">Radeon HD7970 3072MB 384bit OC Boost</a>, then due to a technical issue I stopped mining for a few months and eventually replaced the Radeon with <a href="http://www.gigabyte.com/products/product-page.aspx?pid=4629" rel="nofollow">GeForce GTX770 4096MB 256bit OC</a>...</p>

<p>On which I am currently getting a consistent 126Mhs.</p>

<p>What follows may be a dumb question, but did anything change (eg some network property), that would explain a much lower hashrate on a better card? Or is there something wrong with my setup?</p>

<p>I'm using: BTCGuild and BitMinter, GUIMiner, Win7</p>

Should you be mining Bitcoin with a graphics card? You should look into other more profitable currencies to mine with those...

you need to be using the cudaminer for Nvidia..

and now you should be using x11 to hash..

my GTX650ti went from 200kh scrypt to 1100kh x11 coins..

hit up a multipool like blackcoin.co/mining/

check out <http://www.blackcoin.co/>..

that card should scream.. especially with those specs.. maybe 2.4 to 3.4MH
