Since Zealot seems to be concerned with profit, here's a personal example in favor of mining LTC over BTC right now using the calculator quoted above assuming no cost for electricity and no fees:
GTX 570
BTC:
Hashrate: ~140 MH/s
Coin Per Day: .008 BTC
Profit @ Current Price per day: $0.726
LTC:
Hashrate: 220 kH/s (0.220 MH/s)
Coin Per Day: .613012 LTC
Profit @ Current Price per day: $1.554
As you can see, mining LTC with a GPU is more profitable than BTC (right now at current market prices)
Thank you for that but in the mean time I was so frustrated by the "check the calculator" answer that I googled "litecoins MHs 6950" and eventually found out the MH/s value for my Radeon 6950 2GB.
So I'd be doing 350 MH/s in Bitcoin and 0.42 MH/s in Litecoin. That would be $1.068 net profit for Bitcoin and $2.178 in Litecoin with electricity at 0.10 $/KWh. But here's the funny thing. I have two Radeon 6950 (I only used one in the calculator). And I think one of them doesn't crash with the 6970 bios. So when I hit 710 MH/s I hit parity. Except if my electricity cost in not higher. Because if it's 0.12 $/KWh then I still won't hit net profit parity with Litecoin.
So what do you recommend me?
