I started out buying all the parts listed below, upgrading from my 2500k rig. It is slowly progressing, It's been running since the beginning of this year and will only continue to get better over time.
In November I bought the bulk of the computer of the components, a $55 Fractal Arc Midi, a $100 Corsair HX750 PSU, a $94 Z77 FTW, an $85 3770k, and 16GB of Samsung 30nm ram for $75. Lastly I bought a Zalman NH-D14 copy for $25. I ended up throwing that piece of garbage out and using my old Noctua NH-D14
Total cost of this starter Rig was around $700.
In February I bought three Crossover 2560x1440 displays (which should ran about $1200 for the three), and another 7950 to be able to at least play games on high. The next plans are water cooling for the rig. Either before of after that these 7950s will be upgraded to next amd or nvidia parts dependent on price. SSDs and other items are not planned in the foreseeable future.
I update this as I go along
