ETH requires a gpu 2gb or greater, actually I think it will soon to be 3gb or greater because of something with the size of the DAG
Now with ETC, looking at the difficulty and the network hashrate.... would 1gb and 2gb gpus still be able to mine ETC???
note: I dont really know what the DAG is... is it tied in with the diff and hashrate or is it a block number thing or

2gb will work on etc for awhile, your other issue..miningpoolhub has both on an auto switch port then you can also choose which coin you want paid in so it mines etc when it's most profitable or eth when it's most profitable. I use it and get paid in etc just to help suppress the price of eth as much as I can cause they're dicks. Coinotron has something similar but it just autoswitches and pays eth and etc.
