I understand the font gets very small with the most expensive one. How is the middle one? I think it's the 760 (2.00GHz, 2MB L2 Cache, 533FSB)15.4WSXGA+ LCD . Don't know too much about this. Trying to learn. Appreciate any help. Thanks.
The way the options are listed on the Dell web site have confused the issue for you. The processor options are: 730 (1.6GHz), 750 (1.86GHz), 760 (2.0GHz), 770 (2.13GHz), 780 (2.26GHz). The screen resolution options are: WXGA, WSXGA+, WUXGA. Each step up increases substantially the number of screen pixels, giving higher density, enabling clearer / more detailed screen objects. Note that not every processor option comes with every screen resolution option. The WSXGA+ is a very good safe option. Some find the WUXGA too difficult to configure properly or through choice of software (like Internet Explorer), find, even after configuration, fonts too small. I love the WUXGA, even for office tasks. For CAD I would think the WUXGA would be even more surely the way to go: you can fit a fantastic amount of detail on the screen in high density. I wouldn't recommend the WXGA, which is quite pixelated /grainy in comparison with the others. Every processor option is plenty fast enough for most people. For the few who know what they need (probably including architects), the faster processors will pay big dividends under full load, especially when combined with the 7200 RPM hard drive option. Again, for the rest of us, the 5400 RPM HD is fine. Your initial selection of a "760 (2.00GHz, 2MB L2 Cache, 533FSB)15.4WSXGA+ LCD" would be a very good machine: a very fast processor under full load, and a HD screen - just not as HD as the WUXGA, which one could say is less tolerant but has greater potential.
