The best computers are Dell and HP because they make sure to provide service manuals and are easy to work on. Also, their websites are built great for finding drivers, warranty info, etc. simply by using a service tag.
Just an advice, if you go for buying something related to electronic devices, adjust your budget and your needs. Because "the most suitable choice" depends on both in my opinion. If you have a lot of money and need PC for designing, you may choose Apple for your first option, the second option you may put lower pricing PC in order avoid lost fund unfortunately.
I think only trusted two branded company for this time in market first one is Dell and second one is HP. Yet "what ever" you decide it?
I agree. Dell and HP is the best bet right now for desktop computers. Support is better and as I mentioned before, they are easier to work on and contain large amount of service guides.
Custom is best! HP is good as well, they have a really good warranty and service. Hard to find desktops with lots of memory on pre-made machines
To determine the best PC, we need to understand and know what it the requirements for this PC, is it for Gaming or is it for editing Video or movies or the software that we are going to used would require top of the lone hardware. Planning and information are the best tool to determine the best suitable PC that will satisfy the job requirements.
It's depend on your budget, i think you always have to keep it in your mind first, but in my opinion Dell is the one of best.
Intel Core i7 PC is always the best for you, because of his high-end specification and graphical design compatible and it is used for your business and personal use. and if you are addicted playing games..
