I would like to clear up one small yet very significant detail that this forum seems to have swept underneath the carpet which continues to frighten many people such as yourself, and that is the simple fact that computers become obsolete. When you buy a computer, you must understand that everything about that computer will mean absolutely nothing in 5 years...this has always been the cases and always will be the case.
If I may direct you to Moores Law, after observing the development of microprocessors it was concluded that they should become roughly twice as powerful within 18 months time. If you are worried about buying something because it may one day become obsolete, why do people continue to buy gas powered cars, knowing all too well that natural gas may be gone in less than a century?
My computer does what I want it to do you now, and I feel that what I paid for it was justified. I most certainly don't care about what to expect one year from now or 10 years from now, and I'm not going to worry about it. If I find my PC to be unable to perform some tasks that I want to do, I will make the neccesary upgrades when I need to and when I feel the price is affordable. I don't need to SLI 7800s and I don't need 2GB of RAM and such to be happy with what I do now, and yes, perhaps in the future I will need such neccesities, but why should I buy them now and pay a premium for "futureproofing" when I don't need them now and I can buy them later when they are cheaper
I'm tired of seeing these topics now
