I'm going all out with the 64-bit version of Vista. My PC's been bottlenecked long enough. Hopefully, the new OS will come out by the time I'm finished with my new build late next year. I'll post all the updates on that when the time comes. I've got 3 grand of spending money right now due to the huge retroactive backpay I recieved from work. I'll have more money by then. It's going to be a powerhouse system. Water cooled? Probably not.
