3 290x's and a 4770k. Totally new to mining. HELP

[veedubfreak]

Ok, so I initially bought my 290s when they launched cause I play using 3 27" monitors.  The amount of actual game time I put in is maybe 2-3 hours a day and my computer sits idle the rest of the time.  Someone tell me what I should be mining and possibly direct me to a straightforward "This is how you do this" type of thread?  I keep trying to read up on mining, but it just makes my head spin.

Full system specs.
2 XFX unlocked 290x
1 Powercolor unlocked 290x
3x EK waterblocks
4770k running at 4.3ghz with Koolance 350 water block
4x Swiftech 360 radiators
Enermax Revolution 1100

TIA
