Keeping pace with today's hardware and software developments is not easy.
When do you need to upgrade and when is it worth buying new state of the art equipment vs. upgrading current equipment.
Newer operating systems such as Microsoft Windows 7 have requirements that exceed even the best equipment from even just a few years ago so it makes sense to get the best performance from this excellent OS by using equipment designed for it.
On the other hand if your existing equipment is quite good a simple upgrade of the video or sound adaptor may be all that is required to enjoy the new features.
A technology consultant can provide the facts for you by analyzing your existing structure and offering you several alternatives based on price, performance or both. We do all the work, you make the final decision.
