Anyone offer any advice? We have a Dell desktop that is about five years old. It only has 40gb of memory and even with an external hard drive bolted on it fills up quickly ... most of the memory is taken up with programmes. Don't know what the RAM is but it now runs so slowwwww. It also doesn't have a wireless modem. Thing is we have a huge shed and I want to set that up as an office so we need the desktop to be wireless ... I have a laptop with wireless to use in the house for general browsing and a brand new Acer Aspire One netbook for travelling. So is it worth my while upgrading the existing desktop with more RAM, more memory and a wireless card or would I be better off buying a new machine. How much would an upgrade cost compared to buying new? I am reluctant to buy new if I can upgrade cheaply as, apart from being slow, there is nothing wrong with the Dell. Any help much appreciated as always.
