Ive been mining bitcoins for about a week now and the results are a bit disappointing :/ I have made 0.01382116 BTC which is about one dollar and seventy cents :L I dont know if this is because the pool or my computer
Here are my video card specs i dont really know if this helps


Acording to the wiki
https://en.bitcoin.it/wiki/Mining_hardware_comparison#AMD_.28ATI.29your card should mine between 68-114 MHash/s so
if you go here:
http://www.alloscomp.com/bitcoin/calculatorand use 114 Mhash as your number, you'll get the following based on current price and difficulty
Coins Dollars
per Day ฿0.01 $1.05
per Week ฿0.06 $7.36
per Month ฿0.26 $31.95
So yeah, you won't be making much with that card...
