Hello Twille,
RAM is the first priority. Your current computer has less than the minimum of 4 GB that ANSYS requires. Since RAM is relatively inexpensive, put the maximum that the motherboard can support if you can afford it. My laptop has 32 GB of RAM. RAM is the best investment for reducing solution time. The only exception is if you are limited to the Student license. In that case, you can't solve a large mesh that would require a large amount of RAM.
Fast storage technology is the next priority. You want an SSD rather than a HDD, but you also need a significant size. Start with 256 GB, but get 512 GB if you can afford the upgrade.
Core count is the third priority. Get at least a quad core processor if you can afford it and make sure to set Solve Process Settings to use them.
Make sure the Graphics card has an NVDIA or AMD chipset. Here is the list of graphics cards tested during ANSYS software development.
Good luck, Peter
