After 3+ years of sturdy service from my Scan 3XS system I'm looking to upgrade to a completely new machine. Ideally I would go with Scan again as this current box is the second I purchased from them and they've been good machines, but some cheaper alternatives that I've come across have left me wondering a few things:
1 - Vista or XP? Games are the main thing my PC is used for in terms of demanding performance yet I understand Vista currently has issues with some older and not so old titles?
2 - Core2 or Quad? I'm kinda looking at either a Core2 2.66 or a Quad 2.4 for my CPU. A review I came across on Hexus suggested that game performance difference is minute due to no games being designed to take advantage of Quad-core technology. If I estimate the shelf-life of this PC to be 2 years minimum would it be worth the extra money to get a Quad-core now?
3 - 2gb or 4gb? As I understand it if I want 4gb to work fully I have to get 64 bit Vista which is a minor added cost. Is this right?
4 - Graphics Card? I'm looking for a graphics card that will last me a couple of years though perhaps not as long as the rest of the PC, the graphics card in this machine is not the original one as I replaced it about 15 months ago. Is a 640MB card excessive if I'm not planning to run games at full detail?
Any help or comments would be appreciated.
