Hi guys, I'm hoping to build a new PC very soon and would like to double it up as a bitcoin miner...
Is it still worth buying parts especially for mining? How much longer will it be profitable to mine for the average user?

Probably going to get the HD 5850, what do you reckon?
Should I spend a bit more money and get a couple of SLI'd cards?
Has anyone got a similar setup that works well for them? What are your specs?
Thanks!
