The common question I get is, "what kind of computer should I buy"? Realistically, you should probably upgrade your computer every 3-5 years. However if your current computer does exactly what you need it to do, then just keep it. If something isn't broken, you don't need to fix it right?
As of this time in writing (2014) I've still got my first desktop computer, which I bought all the way back in 2009, but I've upgraded it a fair bit, so it still runs very well.
When buying computers, I find it's best to buy them from a dedicated computer store. You don't want to buy them from a large retail store, because you end up paying much more cash than you need to.
Since technology changes so quickly, in 2014, you can get a pretty basic computer for about $300. These computers are good enough, if all you intend to do is a bit of web browsing, word processing and emails. However, if you want to do video editing, or high-end gaming, you're probably looking at around $500-800+. I recommend everyone to spend that extra couple of hundred bucks to have a really good computer, so that it lasts for 5-7 years, as opposed to going cheap, and only getting 2-3 years of use, and then having to go buy another one earlier than you really need to.
Another common question asked is, "What brand should I get"? Personally, I don’t rate brands because they’re over-priced. That’s why I recommend getting one custom-built from a dedicated computer store. Although if I had to say which brands I prefer, I’d have to say Lenovo or ASUS. If you’re really picky with brands, I’d recommend those two, stay away from HP…
So as of 2014, a good general all round computer will have a dual core AMD or Intel core i3 processor above 2 GHz, with 500 GB hard drive space, and 4 GB of RAM.If you get a system along those lines, then that should do the job for a good few years. But buy a Solid state drive and have that connected as well as the other hard drive to get the best performance possible.
If there's one thing I enjoy with helping clients, its computer shopping, because at the end of the day I know they'll be happy with what I pick out.
Always shop around too, don't buy the first computer you see. If price is a concern, take your time to shop around, but don't spend two weeks of your time trying to save a few dollars. Your time in terms of two weeks is worth more than a few dollars. It's always good to tell the sales person what you want your system to do, this gives them a gauge on what they think will suit you.
So just a few tips for you guys going out and buying new computers, best of luck.
