Please let me know of any issues you see with this build WRT pairing of components, capacity, fit etc. It's an "I need it all" build from CPU to case to mouse. I plan on overclocking, though I don't have experience, it really doesn't look all that difficult w/ lots of good guides and helpful folks out here. =)
It will be our new primary home PC with gaming, some photoshop/picasa work and general home productivity. I'd hope for it to last at least 3-5 years like my current Dell XPS Gen 2 has (but it's old and slower now... =).
The 16:10 format is awkward and from the trends I've seen the market place I would assume its going to be phased out. 16:9 is the HDTV format and the two LCD markets are convergying. If you watch movies on your desktop any movie in the 16:9 format will have a black border around the image rather than full screen. There doesn't seem to be any real advantage to 16:10.
The one thing I might mention some older games don't support 16:9 resoultion like Doom 3 1.1 patch. But thats pretty much the only game that doesn't that I've come across.
