If you are pursuing digital photography, your computer is the engine for your photographic output. It is the enlarger, the developer and all the elements that were part of a film darkroom. Yet this most important part of your digital darkroom is pretty well ignored by the photographic media. Of course there are thousands of videos and a million written tips about how to edit Photoshop on a computer but very few articles and videos on what exactly you need for a computer. One of the lone voices is Imagescience.com.au which discusses computer options and sells computers.
Obviously I would not recommend buying a computer from Australia or anywhere for that matter. I recommend build your own!! Pre-built computers for sale always compromise component quality for the optimum price point for a profitable sale. You can take the time to search for the best and most reliable product for your computer and at the same time while building the computer you will become very knowledgeable about how your computer operates and you become the builder and maintenance custodian for your photographic pursuit and passion. If you take your time, building your own computer can be very easy and extremely fulfilling in your accomplishment.
Your main computer should be a desktop. As far as I am concerned, a laptop is only for field work and travel. Sitting on your couch, laptop on your lap, sipping a beverage while looking at screen where you will miss the small edit adjustments which would be essential to your photographic editing because the screen is so damn small, is not the best minded approach to achieving your photographic excellence. Commit to a solid stable environment, your own digital darkroom and you will see positive creative developments. 27" minimum size monitor, at least 64 GB of memory and 5 solid state hard drives would be a good start. I have 3 NVMe M.2 1TB a piece Samsung solid state hard drives on a MSI motherboard, 2 SATA Samsung solid state hard drives as storage for photographic work and music files, EVGA 750 watt power supply, Noctua cooler, Corsair memory-64GB and a very big Phanteks case which really made it easy to work in. I mention brand names not to brag but to give you excellent reference points for very reliable products. Absolutely no problems in 4 years of operation which is almost the normal shelf life for most pre-built computers being sold like Dell, HP, etc. From my research and it is only getting worse, I can also name a product to absolutely avoid, Gigabyte. Nothing but crap especially their power supplies. Can you imagine taking a bathroom break and returning to find your computer on fire because the power supply overheated. Their motherboards are a constant problem and are found in many of the pre-packaged computers sold. Do not even think about calling customer service!! Research and time prevented me from buying their dangerous and junk products. Jaytwocents and Paul's Hardware on youtube are excellent and entertaining sources of information. PCPartPicker.com is an very good website to start determining your build and parts compatibility.
Now unfortunately building a computer is a lot more difficult task to accomplish now because of the exploding prices of graphics cards due to the insane escalation of crypto currency mining, AI and the shortages of memory chips. So your plans for building a computer will most likely extend over a longer period of time but the wait and the time I think still would be very beneficial. More time to research and find the best possible product at the best possible price. And if you think I am some young computer geek trying to have you do something beyond your capabilities, I am 73 years old and if I can do it and enjoy it, I am pretty sure you can too.
P.S.- The links and products I provide and mention, I receive absolutely no!! financial compensation for. If I recommend something it is because I find it to be of real value and interest. I can be this independent because I do not need a revenue stream from this site. Trying to promote a revenue based business, the financial compensated links are a real necessity in the digital business model along with advertising unfortunately.
