The New Alienware X51

Alienware has just launched the new X51, which is a console sized gaming PC.
X51 comes with either NVIDIA’s GeForce GT 545 graphics in the cheaper model, or GTX 555 in the top end specs. Prices start at £699 (no US price has been confirmed yet) which is just ridiculous for what you're getting.

Everything is upgradeable just like a regular PC, but will it run as quiet?

If you're interested in buying one (may god help you), you can get them here, and customize them.

Valve announces Counter-Strike: Global Offensive

 

VALVE ANNOUNCES COUNTER-STRIKE: GLOBAL OFFENSIVE (CS: GO)

Next Gen Console, PC, and Mac Release Targeted for Early 2012
August 13, 2011 – Valve, creators of best-selling game franchises (such as Counter-Strike, Half-Life, Left 4 Dead, Portal, and Team Fortress) and leading technologies (such as Steam and Source), today announced Counter-Strike: Global Offensive (CS: GO).
Targeted for release via Playstation Network, Xbox Live Arcade, and Steam (for PC and Mac) in early 2012, CS: GO will expand upon the team-based action gameplay that it pioneered when it was launched exactly 12 years ago (CS beta 1, August 1999).
CS: GO features new maps, characters, and weapons and delivers updated versions of the classic CS content (de_dust, etc.). In addition, CS: GO will introduce new gameplay modes, matchmaking, leader boards, and more.
“Counter-Strike took the gaming industry by surprise when the unlikely MOD became the most played online PC action game in the world almost immediately after its release in August 1999,” said Doug Lombard, VP of Marketing at Valve. “For the past 12 years, it has continued to be one of the most-played games in the world, headline competitive gaming tournaments and selling over 25 million units worldwide across the franchise. CS: GO promises to expand on CS’ award-winning gameplay and deliver it to gamers on the PC as well as the next gen consoles and the Mac.”
CS: GO is being developed by Valve in cooperation with Seattle-based Hidden Path Entertainment. The title is targeted for release in early 2012 and will be playable at this year’s PAX Prime and London Games Festival.

Counter Strike. One of my all time favourite games, But how could they possibly make it better? Don't like the idea of it being on consoles much. It's their second try on this. And the first one didn't go well. We'll see. I'm excited nonetheless.
