310 Mhash/s is $0.01 per day?

maybe u can buy an ASIC, sha 256 or scrypt,
but no guarantee for asic too, because if we use a GPU, maybe u can sell it again if we want change,maybe to other gamer who need it,if asic,u can't sell it again,
so,which the best, u decide again,

You can get a lot of these card on the cheap on eBay due to all the miners dumping them.  Scrypt hashrates are going up with ASICs now.

The problem with this is that even if you get the cards cheaply they are still unprofitable to operate.

That's why they're dumped on eBay and not here saving the seller a 20% fee.  When there was a shortage you could sell a 5830 on here and now there's a glut of cards.

I guess the very small miners are basically a suckers game.

you should try mining altcoin
dogecoin can with mine and exchanged at the currency exchange

So according to a lot of popular profitability calculators taking in current exchange rate and difficulty settings, I will be losing money at 310Mhash/s with my Radeon 7800 Series due to power costs. Should I trash this card and get a different one? Or throw out GPU mining altogether and go with an ASIC?

You can always look into the other Algo's…. x11, X13 Scrypt-n, Groestl, Keccak, Quark and exchange those for BTC. Waffle-pool multi mines Scrypt-n and X11 and I think they are working on X13. Do a little investigating before you just trash your cards
