Currently have a 7750 GDDR5. I'm beginning to mine Litecoins (LTC) should I get a $130 7790, $170 6950, or $240 7950. After rebates and selling the games.
I'd like to see the answers here. I saw some boards you could buy for mining that claim they could pay for themselves in days and provide you with a few hundred a week. Too good to be true.
