I just ordered a new computer (CPU, GPU, RAM, ...), but it won't arrive for another week. I also want to buy an SSD though. If I buy it now, and install Windows 7 on it, will I have to reinstall it when I get my new parts so that it recognizes and installs the drivers for them?
Windows installs pretty quick on a SSD. Just learn some patience and wait a week, then set everything up. You wont save any time by installing today if you have to spend a bunch of time finding drivers and fixing everything that is broken when you put the drive in the new PC.
