I wouldn't really call the lynnfields "old." The lynnfield line of nehalem cpus was introduced late last year to accompany the bloomfield nehalems, and are still one of intel's top-of-the-line cpus.
The mobility 4850 was intro'd early of 2009, and will likely get replaced by mobile 5k card, but that still doesn't take away the fact that it's an elite class mobile gpu. Mobile 5k card won't be much more powerful.
