I'm already getting the "Intel® 45nm "Penryn" Core2 Duo T9300 2.5GHz w/6MB L2 On-die cache - 800MHz FSB" in my new Sager when I buy it. But I was wondering about the "Intel® 45nm "Penryn" Core2 Duo T9500 2.6GHz w/6MB L2 On-die cache - 800MHz FSB" which comes for an extra $225. Now it has the same cache and the clock speed has a really tiny increase. Is this really worth it, because I might just be ready to spend for it. Nothing really special about it, right ? It's not Core 2 Extreme or anything? And a side question, what exactly is so special about core 2 extreme (other than higher clock speeds) ? Is it available as a notebook processor? And the quad core ?
