Here is what you'll need;
*new motherboard - Get one of the newer ones with B3 stepping and pay the extra $20 to get one that is capable of working with an unlocked chip. Ensure that it has at least 4 slots for DDR 3 RAM, two or more PCI express ports, at least two SATA 3 connectors (one for your hard drive, one for your back up), 2 or more SATA2 connectors for your other peripherals (you'll need at least one to plug your internal DVD player into) and several USB plugs - I got a gigabyte GAP67xUD3R-B3 for a bit over $200.
*A new CPU - either AMD or Intel (match it to your motherboard and get the right cpu socket!). I went Intel with an 15 2500k for $220. Note that the k series in Intel gives you the ability to oveclock your chip. You can get an 17 unlocked for about $330, but whats the point unless you use it for work and seriously multi-task. For gaming, a quad core is probably going to suffice because its actually you graphics card that will do most of the heavy lifting. Your processor should come with its own cooling fan in the box
* New power supply - Your existing supply in your old pc will be about 300watts, so you will need to upgrade. You will need at least 500watts for your board and another 250w or more for your graphics card. Do not buy a cheap power supply. Be prepared to spend $100 to 150 bucks from a quality manufacturer. Buy cheap and likely, you will get the blue screen of death first time you boot your new pc up. It should come with all the necessary cords and plugs.
* A new case - your new motherboard will be unlikely to fit in that old case - New antec or coolermaster etc for about $100.
* New DVD burner $40.
* New hard drive ( I got a 2GB Western Digital Green for $84) and re-used a 1GB spare from my old machine. Sure, get a solid state disk if you have won the lottery. Note, do not instal your OS on any hard drive greater than 2GB.
* New RAM. I got 4GB's of DDR3 for my 32 bit system for $50 (1333mhz) Sure get 16GB+ at 2133mhz for $100+ if you can afford it and you process a lot of video footage on a 64 bit operating system. I don't however and 4GB is just fine.
* New video card - any of the newer ones with crossfire X or nvidia equiv - don't skimp here, get the best you can afford. Also check the outputs on the card match your existing monitor (RGB, DVI, HDMI).
Be prepared to spend from minimum $150 to $300. Pay much more if you are into graphic intense 3D games. Buy two and link if neccessary.
