Mining questions

[Vistination]

So I just started Bitcoin Mining. I am using a 7870 with BitMinter. For some reason, I'm only getting .038 Bitcoins a day when others with the same card are getting around .2 per day. Why is this? Also I'm at 363 Mhps

No. You are actually getting exactly what you should. I have a spreadsheet I use to keep track of everything bitcoin including a calculator based on future and current difficulties. My calculator says that at the current difficulty you should make 0.037659034 BTC/day at 363MH/s.

I have 800-900MH/s going and haven't been able to get near 0.2 BTC/day for a few months now.

The hash rate is going up, so your mining potential will decrease.

The rate will continue to rise as more ASIC miners come on line.  this is why people have been warning against starting in GPU mining.

Yep, unfortunately thats about right for a 7870.

GPUTweak is a doos utility from ASUS to help get the most of your card. Increase your intensity as well and you may get closer to to 400Mh/s. But there is no way 400 or even 500 Mh/s will yield 0.2 btc per 24 hours. 500Mh/s like a 7950 will yield approx. 0.05BTC per 24 hours.

Don't worry, everything is fine. The total network hash rate has increased dramatically recently, as has the value of BitCoins. I believe GPU mining is still viable, especially if the cost of electricity is fairly low for you (it is for me), because 1 BTC is worth a LOT more than it was just a few short months ago...

Yeah I'd say pretty luckily it seems that the price of one coin is tied to the amount people are investing into mining them.  Thus more asics means a harder hash pool but also a high price.  You might want to check out litecoins as a potential alternative, since some people are switching into mining them with GPU's as they remain profitable (also, they have the potential to start catching up with bitcoins)

I get ~0.2 - 0.4 a day on p2pool having 6GH/s so your numbers are correct (sadly)
