i think this says it all really..
"Multi-core computing is the new standard for PC games, and we at Epic are thrilled to see Intel leading the industry forward with Core 2 Extreme. Its four high-performance CPU cores enable a new level of realism in games, with realistic physics simulation, character animation, and other computationally-intensive systems."
- Tim Sweeney, Founder and President, Epic Games
"The introduction of Quad Core processor based PC's allows Remedy to create real next generation games as demonstrated by our "Alan Wake", a psychological action thriller to be published by Microsoft Game Studios. Dividing complex programming tasks into multiple threads is the way to exploit performance that allows us to create more realistic and dynamically generated environments - and thus enjoy fantastic game worlds like never before."
- Markus Maki, Development Director & co-founder, Remedy Entertainment
"Gas Powered Games has had the opportunity with our Supreme Commander title to be on the leading edge of working with Intel's Quad Core. The performance and experience enhancements we've seen implementing our multi-threaded architecture on Intel's multi-core systems has shown us that these technologies will represent the minimum bar for the future of advanced gaming."
- Kent McNall, President, Gas Powered Games Corp
"Gamers are asking for more and more realism and immersion, and this of course requires even more power and speed. To meet their expectations, we optimized our more demanding games for multithreading. In this way, Ubisoft can take full advantage of the architecture of multi core processors such as Intel Core 2 Duo and Intel Core 2 Quad Extreme"
- Vincent Greco, World Wide Production Knowledge Mgr & Technical Coordination, Ubisoft
"Quad-core will change every aspect of PC gaming. It will change how we create our games, how we provision our service, and how we design our games. The scalability we've seen in graphics over the last few years will now extend to physics, AI, animation, and all the systems which are critical to moving beyond the era of pretty but dumb games."
- Gabe Newell, president and co-founder of Valve.
