I'd like to start mining Altcoins with a spare PC, nothing too expensive to start with.
Something where cost is a more important factor than Hashrate.
The PC is an Intel two core E5300 2.3Gh
Something that will give me an edge over CPU mining which I've tried with minergate giving me around 10 H/s
![Undecided](https://bitcointalk.org/Smileys/default/undecided.gif)
but which ties up my CPU
which I'd like to use for other stuff like managing a couple of POS wallets.
I'm looking to mine coins as a long term investment rather than to sell immediately.
Oh yes, something flexible with regards to Algorithm.
Any suggestions on a GPU I might be able to pick up cheap to improve on CPU mining.
