Being old is not reason to scrap it. Not doing what is requireed or desired would be.
Exactly Nemesis.. Office 2007 requires a better performing machine.. not an outdated one..
Most of your programs coming out today require Core 2 processors or better, many graphics based software are starting to require SLI x3 in order to get full graphic capabilities.. many more programs are starting to require 4GB ram or more..
Age of Conan for example.. works best on a maching running 2 vid cards in SLI with 1.5 GB video memory per card.. preferably the GTX 295 series for the fast graphics processing.. 8 GB DDR3 memory and an i7 quad core CPU running off the 980 Intel chipset at 3.6 Ghz...
However you can play the game with Med to med. High settings and Direct X 10 using 1 NVidia 8800 GTX with 512 MB memroy or better, a Core 2 Duo running at 2.4 GHz and 2 GB system memory.. but expect low fps and expect some latency if you are using an integrated ethernet card.. the CPU just can't handle it all.
With Office 2K7, the program is Multi-Threaded and Optimized for 2 or more processors.. thus works best when running it with a Pentium Dual Core (which only lasted about 6 months on market) or the Core 2 series CPUs that have either 2 or 4 CPUs in 1 die..
Software is being designed to take advantage of the innovations of hardware, and in some cases like Age of Conan, it is being designed to work on Modern systems build within the last 2 years or so with the outlook of having to allow it to run on systems 10x better than what is on the market today.. so their game is extremely demanding on hardware and specifications.
Now if I was an old company that has no vision of the future and likes to work at turtle or snails pace.. the yes, I would keep a Windows 3.1 or 95 /98 machine going to take care of my business.. or if I want precision, and to be able to increase the speed and effeciency of my company, I could update my equipment to something that offers me more independance, flexability, speed, stability, and have the capabiolity of doing more than 1 project at a time.
Imagine your work Win 98 PC.. it can do what, 1 at a time?, with a Quad Core system with 4 independant processors. you can be doing 4 at a time... your productivity just quadrupled..
Which is why older systems are scrapped out, and the parts melted down as much as possible and recycled into new components...
If we are talking about people, I agree, You don't thow out because its old.. but looking at Technology.. Old is not better, it is just Much, Much slower and incapable of performing as well as a newer piece of Tech..
Like ToastyO stated.. it is like comparing a steam engine train to the bullet train.. I get on 1 train, you get on the other.. we are both leaving from the same place to get to the same destination 400 miles away.. I should arrive there many, many hours ahead of you because the technology allows me to travel at 200 Mph compared to the 60 Mph tech you are using. Sure you get to see more of the scenery on the way, but think of all the productivity time lost. Because I used newer tech to travel, I saved 3 hours and 40 min.. thus more time for me to be productive.
Just something for you to think about.
