Ebayers,

As a PC Salesperson I will give you the guide that we don't normally share, hell it is commission after all...

FOR THE FAMILY THAT

JUST DOES WORK NO PLAY - AT LEAST Intel Dual Core or Athlon X2  (NO CELERON OR SEMPRON) at least 1GB RAM and 120GB HDD, DVD Burner is normal and most other options are standards now, graphics will be of no interest to you with screen spend no more than $1500RRP for a brand new machine, on ebay you will find vastly superior machines but buyer beware on the warranty!

I DO SOME PLAY AND WATCH A FEW MOVIES ONCE A WHILE - AT LEAST Intel Dual Core or Athlon X2 (AIM FOR CORE 2 DUO [high class core duo]) 1GB Ram (2gb pref.) and at least a 160-200Gb HDD Graphics at least 128mb Dedicated (this will seriously boost your systems speed by taking picture effort off your motherboard, like having a labourer moving the bricks for you!) You may spend $1200-$1700 with screen RRP

I EDIT MY OWN HOME MOVIES AND PLAY A BIT MORE - AT LEAST Core 2 Duo or Phenom Quad Core 2GB Ram and a 320GB HDD Graphics at least 256mb pref 512mb be prepared to spend $1500-$1999RRP

I'M A FULLY SICK HARDCORE L337 GAMER!!! HAXORZZZZ!!! - Aside the fact you wouldn't be using ebay for your pc parts anyway i would recommend at least... Quad Core Intel or E6800 or above C2D, 3GB RAM (Windows can only support up to 3gb, so no purpose going higher it's wasted) 1TB HDD and 1gb Graphics or 1.5GB DUAL CARD expect retail wise to spend $2000-$3000 solely because of the CPU and GPU.

So try and find the category that best suits you, if you ever get stuck I work for shop called Clive Peeters, so email me on ebay or call the store 02 8887 7300 Ask for Stu or Alan and we can give you more info regarding this guide.
