Soo all in all I have fallen in love with the whole idea that is BitCoins and I want to start mining (I already am but only at 1.5 mhash/s... which is sad). For starters here are my current PC specs
Its an ole Dell XPS 400
Manufacturer Intel(R) Pentium(R) D CPU 2.80GHz
Clock Speed 2.8GHz
Pretty sure its a dual-core
Got 1 gig DDR Ram
AND running a Geforce 7300 LE running on PCI-E 2.0 im pretty sure with 512mb
Typical optical drives, usb's, HDD
On the power supply it says that its peak is 150W. I personally think its 300, but its stock regardless
Whole systems stock
Running XP SP2
AS for the MOBO I dunno, I think it has multiple PCIE slots
(Mind you I'm not considering a sole mining rig, I will also be using it for typical use, nothing too demanding in terms on gaming or video processing.)
For starters we got a $500 max, however im really just thinking I need a better power source, another gig or two of ram and a 5850 possible dual
Thanks for any input, I greatly appreciate it
You'll have a tough time finding a decent 5850 (expect 250-350 MH/s out of it after overclocking), but last I checked, it's the most cost-efficient miner you can get and sips power relative to other cards. You will need a better power supply (look for at least 400w+ if you get just a single 5850 -- should have 80+ certification and Active PFC if you live in an area where electricity is expensive, or you care about the environment [lol]).

RAM is useless in mining. You'll probably want to pull out your other gfx card. It's scrap at this point in time (though useful if you just need something to display information). For mining with a graphics card, you'll need an OpenCL miner. Google "GUIminer download" for one which is extremely easy to use.
You'll want to join a pool, too. I personally like BTCMine.com but check out the different pools and decide for yourself.
PSU & graphics card should cost at or below $275 combined. Make sure your case can house as large a graphics card as you buy. Some retail PC manufacturers use proprietary power supply designs which make it difficult and expensive to upgrade -- I'm not sure about your Dell XPS system.
