Basically exams are over and it's something i've always fancied doing but i've got only very basic knowledge in this area, i was stunned that after installing a graphics card nothing blew up.
Anyway, i'm fine with the whole putting it together but i have no idea about setting up a bios or installing an OS so thats the main area i'm enquiring about, whether you yourselves can help or point me to an (up to date if possible) guide. Or even just a very basic version of the steps i should be taking in which order.
Also here's my chosen bits and bobs, i've probably missed something out and if any of these parts are terribad i'd appreciate some input.
Mobo: MSI P35 Diamond
Graphics card: i have a 8800GT already that i can whip out my old pc
Processor: Q6600 Quad core energy efficient version
Sound Card: Creative Soundblaster X-Fi Xtreme Gamer
RAM: OcUK 4gb 800mhz DDR2 RAM
On a side note with the RAM, whats the difference and what should i be buying between DDR3 and DDR2?
PSU: OCZ GameXStream 600w Silent SLI Ready ATX2 Power Supply
Case: Antec Three Hundred Ultimate Gaming Case
OS: Windows Vista Ultimate, but which should i get 32bit or 64bit and what's the difference?
Cooler: Arctic Cooling Freezer 7 Pro CPU Cooler (Socket LGA775)
I'm gonna want to have a go at overclocking in the future so will i need some of that thermal stuff for the CPU?
And lastly, i've not much of a clue on compatability on pc's so if any of these chosen parts don't look compatible that'd be awesome for someone to point out

Thanks for help in advance
Olly
