For the second week in a row, the TweakTown System Builders Guides have been updated with some pretty significant changes.

Besides the usual round of price updates for the products that don't have their prices updated automatically, the TweakTown Sub-lieutenant PC ($1000 USD) is the first to get the treatment. Out is the OCZ memory since it is out of stock and may never return due to the recent announcement of OCZ quitting the RAM business during CES. In its place is a Kingston HyperX 8GB (2 x 4GB) DDR3-1600 Dual Channel Kit. Yes, 8GB of RAM now in the TweakTown Sub-lieutenant PC!

Moving onto the TweakTown Commander PC ($2000 USD), the previous set of Logitech speakers have been removed since they are no longer being sold and in place of them is the Logitech Z506 75 watts RMS 5.1 Surround Sound Speakers. A really solid choice considering the price range we have to play with in this system for this component.

And finally we meet up again with the TweakTown Admiral PC (Unlimited Cost). Intel quietly released its newest processor this week, the Core i7-990X Extreme Edition 3.46GHz Six-Core. It runs more expensive than the previous 980X CPU which was used and of course comes with a higher clock speed.
