850W Power Supply should be more then enough, make sure it is a decent make though. My Case came with some KICKASS Antec ones, what case are you going for?
The watercooling just means my system will be quiter and provide greater cooling performance. My CPU will stay at lower temperatures for longer even if the CPU is kicking out more heat. This does however depend on the efficieny of the CPU Block and Radiator etc. So, try to go for decent makes with proven technologies. Reviews are really useful in this area.
Veloci-Raptors! Wow, although the performance I see with my Raptor is almost the same as the 1TB Seagate, but games and operating system all in all load extremely fast. As for the game, it did it with pretty much every game, some quicker then others. I am going to roll back to Vista x86 32bit, and hope that the problem clears itself. Think it is mainly due to 64bit systems not really taking off, or becoming the 'Standard' as it were.
Thanks for the reply, shall keep you updated if anything else pops up.
