cheap gpus for xmr? the complete AMD GCN 1.0/2.0 bouquet:
7850, 7870, 7870XT, 7950, 7970, 7990
R7 265, R9 270, R9 270X, R9 280, R9 280X, R9 285 (gcn 3 but doesn't matter), R9 290, R9 290X
R7 370X, R9 380, R9 390, R9 390X
they do all over 420 Sol/s, the bigger ones even up to 900.
Great! I assume that all these have only 2 Gb?? I don´t know alot about the monero DAG size or the expected increases either. I could google it, but I like hearing from people on this forum.
