Ive just ordered my parts for a new build, details below if your interested.
Intel Core 2 Quad Pro Q6600 "Energy Efficient SLACR 95W Edition" 2.40GHz (1066FSB)
Asus Maximus Formula SE Intel X38 (Socket 775) PCI-Express DDR2 Motherboard
2 x Crucial Ballistix 2GB (2x1GB) DDR2 PC2-8500C5 1066MHz Dual Channel Kit
Seasonic M12 Modular 700W Silent ATX2.0 Power Supply
Antec P182 Super Midi Tower Case - No PSU (Gun Metal Black)
BFG GeForce 8600 GTS OC2 ThermoIntelligence 256MB GDDR3 HDTV/Dual DVI (PCI-Express)
Now to get to the interesting part.
I mentioned a while back that once i got my new build sorted i would do a comparison of XP and Vista 32 and 64bit, to see what differences there were on a decent system. What im wanting from you guys and gals are things that you want me to compare between the OSes. So fire away.
