What tech specs would you need in your pc to run windows 7?

No idea at all. Your computer should be fine. Microsoft wouldn't release an OS that most of the population couldn't use-oh wait...

I wouldn't be too concerned right now its not set to come out for roughly three years. Hardware is expected to last about that long and by the time it does come out yours will be obsolete. Just wait and you will be privy to the system requirements for it.

you can install LINUX

I would say the thing you would need to change would be the CPU as it's a 2.3Ghz I use a Quad core 2.4 and it manages to run Vista Ultimate. I had to change my PC dramatically just over Vista Ultimate. People would say it wouldn't be worth it. It depends on how you feel about it all. I would say for you, after you change your CPU then you have really no worry to install the next Windows but nevertheless it is Microsoft after all. Who knows what you need to run the next version of Windows. I can tell you though, many companies have made money from Vista of having to upgrade their parts, either installing new RAM or graphics card. Companies who make these won't be out of pocket.

Well, I assume at MINIMUM what the (ridiculous) requirements for Vista are. By the time they release the next version of Windows, the requirements will probably be much higher I'd imagine. >.> Home Basic: * 1 GHz 32-bit (x86) or 64-bit (x64) processor * 512 MB of system memory * 20 GB hard drive with at least 15 GB of available space * Support for DirectX 9 graphics and 32 MB of graphics memory * DVD-ROM drive * Audio Output * Internet access (fees may apply) Additional Requirements Actual requirements and product functionality may vary based on your system configuration. Windows Vista Upgrade Advisor can help you determine which features and edition of Windows Vista will run on your computer. While all editions of Windows Vista can support multiple core CPUs, only Windows Vista Business, Ultimate, and Enterprise can support dual processors. Vista Home Premium / Business / Ultimate * 1 GHz 32-bit (x86) or 64-bit (x64) processor * 1 GB of system memory * 40 GB hard drive with at least 15 GB of available space * Support for DirectX 9 graphics with: o WDDM Driver o 128 MB of graphics memory (minimum) o Pixel Shader 2.0 in hardware o 32 bits per pixel * DVD-ROM drive * Audio Output * Internet access (fees may apply)

a new microsoft os is years in the future pointless to concern yourself with it now. as far as upgrade advice get a core 2 duo e8400 they use the new 45 nanometer technology they have 6mbs cache and are easily oc'd to 4GHz, you will probably need a new board but it is totaly worth it these cpu are next generation.
