If you go
http://www.alloscomp.com/bitcoin/calculator.phpinput the next difficulty level - 1167734.0, and 300 Mhash/s (max rate for 5830) and $18 per bitcoin which IS $4 more than they are currently trading for. You get
Coins Dollars
per Day ฿0.26 $4.65
per Week ฿1.88 $33.92
per Month ฿7.86 $141.40
So, it will take 1 month of mining with no difficulty increases just to break even...lol.
I will wait patiently as I will snag 2 of these cards for nothing. They are not good for gaming so they are useless outside of mining.
Hi
Ok, troll, let's run that game with the specs for a 6830.
Same difficulty: 1167734
6970's max rate: 420 mHash/sec
Exchange Rate: 18
Troll (hi/angelus) gets:
Coins Dollars
per Day ฿0.36 $6.56
per Week ฿2.66 $47.82
per Month ฿11.08 $199.37
Spending $300+ (not including shipping), and you break even Tuesday after thanksgiving, troll.
So, by your math and horrible-theorycrafting-type-soothsaying-of-things-you-know-not, not really any card is worth it. Keep circle jerking and posting on everyone's 5830 post and you'll be SOL with all your waiting. Good luck, troll, and next time you sell your 5830 for $50 stop and think about it for a sec, instead of trying to rain on everyone's parade.
