Intel's Penryn Benchmarked 124
Steve Kerrison writes "Intel's keen to show off its up-coming 45nm Penryn Core 2 CPU. HEXUS had some hands on time with the new processor to get an idea of how well it will perform once its released: 'Intel's new 45nm Penryn core adds more than just a clock and FSB hike, so much so that even a dual-core Penryn is able to beat out a quad-core QX6800 under certain circumstances.'"

Why is that a problem? It isn't like SSE2 is going away just because SSE4 is coming through the door. And it isn't necessarily the case that SSEx+1 is "better" than SSEx, since the different SSE instruction sets may have slightly different target applications. One project may mostly benefit from SSE2, while another may mostly benefit from SSE4. Some projects may not receive any benefit from certain SSE revisions, and thus wouldn't care to implement them.

More speed will certainly allow me to open more windows at once, along with a increase in RAM. The performance should be a boon for gamer and science communities, though. Optimized your app for this processor and watch the simulation fly! Is there anything in most OSes that could benefit from these advanced optimizations?

Over the desktop? Not really, given how much the market has increased in recent years. The price of a laptop is not far over the prices of a comparable PC, hard disk space and GPU power is enough that most people don't have to compromise.
There's a few reason to have desktops:
1. Large monitors
2. Large diskspace
3. Better graphics cards
4. You want to tinker with it, upgrade etc.
But if you're not really falling into either of these four, there's not really much of a reason to go with a desktop, unless you know it'll be fixed in one location 90% of the time. Many people don't have a dedicated "computer area", they sit down at a suitable desk, use it then afterwards pack it away. Many people want to take it places, school, work, friends, cabin, road trips, whatever. Most people want that over the three 5 1/4" bays (DVD-burner and ???), four 3 1/2" bays (2-500GB disk + ???), 7 PCIe expansion slots (GFX card + ???) and all the other empty space they get in a desktop.
