Not really dude, a lot of programs are being coded with dual/quad cores in mind. They are more efficient at running more than one thing at a time. I mean honestly who uses the internet and nothing else?
Sounds like you have a nice computer bro. I built mine last black friday for 500 and I got 8gb of ram, 3.0 ghz quad core...its is beautiful.
99,9% of people who own a computer ? doing some excel word or powerpoint or any management software doesnt require much power from the cpu nor gfx card nor a big amount of ram either.
That's why most pre assembled computers in offices just have a decent CPU and screen with all the rest of the computer being pure crap.But that's enough for pure office use.
Most people who own a computer at home only surf and do some clerical work, sometime watch a DVD or div x, but you could do that with a pentium 500mhz from 1998 ...
Fact is you only need an homogeneous computer with a complete set of powerful parts (huge cpu that is dedicaced to manage huge and complicated loads of tasks,gfx card, ram, fast harddrive) if you play video games and do video editing.
Even webeiditing and sound editing doesnt require powerful computers, only an average main CPU.
Also, put aside profesional sound or video editing softwares, and video games, most applications arent even coded to take benefit fromt he use of multiple cores and the last technolgies embeded in the newly released CPUs.

ordered it 4 months ago, i bet it's even cheaper to build the exact same computer right now. Keep in mind i ve been into computers and web programming since 1995 ...that's why i know that the most important thing before building/buying a computer is to know what it will be intended for. This way you know what is required, and what is not, thus being able to pay exactly the amount of money required for your use.
