Computer replacement!

[Concillian]

I plan on using 7, and don't want to put much time into learning Vista if I can help it. I'd really rather just set my PC up on windows 7 RC, but that seems a little risky :-P

One quick questions, can anyone explain the difference between DDR3 1333 and DDR3 1600... I'm researched out atm...

Win7 is essentially Vista with some changes. It's like Win2k vs. XP. Same guts new facelift. Vista became a bad word, so they called it something else, but they aren't fundamentally very different. You don't have to re-learn much between Vista and Win7.

Memory speed differences are generally very small performance improvements in terms of overall usable speed. The difference between 1600 and 1333 is just clock speed, much like the difference in processors of the same "line" is just clock speed. The actual application performance differences between fast and slow memory is on the order of 1-2% unless running very specialized applications that stress memory throughput (generally a zip / unzip or rar / unrar type application). Typical general use apps are not usually very dependent on this aspect of performance. This is part of why the market as a whole has been very slow in the DDR2 --> DDR3 transition, there's very little performance reason to go DDR3.
