Processor- You have to go at least Intel Core i5 8th Generation or above generation processor for a beginner and those having not more budget to spend.
For Professional and higher budget go with Intel Core i7 8th generation and above.
RAM- You have to go with at least 8 GB RAM for a beginner and those having not more budget. It is capable to handle only one program at a time like photoshop or illustrator easily.
For a professional and high budget go with 16 GB or 32 GB RAM for superior multitasking at a time.
GPU- I have heard a lot of question, I m gonna be in Photoshop and gonna be working on illustrator. Do I need a GPU? What GPU is good for photoshop or illustrator?
It doesn’t matter the Integrated graphics is enough. The reason you want to get a dedicated graphics card like NVIDIA GTX graphics or AMD Radeon pro is for video editing. When you working inside a Photoshop Indesign or illustrator you are relying too heavily on your CPU, the GPU only comes in when you are rendering video or when the CPU gets overloaded saying Premiere Pro or DaVinci Resolve the GPU will come in and support the CPU alongside it to run faster, it also runs multiple screens so if you are running multiple screens on your laptop and you are editing 4K footage then you need a bigger graphics card to make sure your computer keeps up and doesn’t start to get laggy in the timeline of Premiere pro.
So no you do not need a GPU If you are in basic Photoshop and designer illustrator programs, it’s only when you getting into the video editing.
Storage- I recommended avoiding the HDD drive going to the SSD drive that becomes so affordable in this day, they perform much faster than HDD drive.
