Hey,

IMHO your proposed rig sounds way over specced for a dedicated mining rig! If you use it for gaming as well as mining then OK, but as a dedicated rig its probably a waste of money. 

I spent £380 on a dedicated, low power rig with the following spec:

CPU: Sempron 140 (cheap and draws very little power)
Mobo: Gigabyte GA-870A-USB3 AMD 870 (x 4 pci-e slots, includes 1 x16, 1 x4 and 2 x1 slots)
PSU: 800W Corsair GS800 (decent power supply a must, this one is 80% and relatively cheap)
Memory: Corsair 2GB DDR3
HD: Seagate 1TB 3.5" Sata-III 6GB/s Barracuda Green Hard Drive - 5900RPM (low power and cheap)
GPU: Two XFX ATI Radeon HD 5830's (picked these for £71.99 each new, not the greatest GPU but gives the best £ to performance ratio of all GPU's)

This set up gives me around 650 MH/s and produces around 0.45 BTC per day at current difficulty running 24/7, with the option of adding 2 more 5830's at a later date (when I have abit more cash handy)

As for your mining options, would recommend that you stick to a pool as solo mining is somewhat of a gamble unless you have hundreds of GH/s at your disposal. A pool will give a much more consistent payout, my recommendations are www.bitcoins.lc (0% fee but bitcoin payout can be a little erratic due to them having a lower pooled power of around 500 GH/s on average) or www.btcguild.com (they have around 3,000 GH/s, more pooled power = more consistent payouts)

Good luck! 

*Edit - the CPU I meant was an Sempron 140*

I'm very new to mining and its about the time of year i upgrade my PC and i was looking into
building a dedicated mining PC.

Here are the proposed specs:

AMD Phenom II X6 1100T
Gigabyte GA-990FXA-UD7
8GB Corsair DDR3
Powercolor Radeon HD6990 4GB x2 maybe a third later on this year
Silverstone Strider 1200W Gold
Most probably running windows 7

inc HDD and Case it comes to around $2500 Australia Dollars

I would like to know how profitable mining would be with a rig like this?, would it be better to mine
in a pool or solo mine ?
What would income figures look like ?

Thanks,
