What factors affect the general performance of contemporary desktop systems? Of course, it is first of all the CPU and graphics sub-system. The CPU determines how fact the computer can process data in computational and system tasks, while the graphics card determines the result visualization speed. Obviously, if we are talking about applications processing and creating content, the role of the graphics accelerator becomes secondary. If we turn to entertainment applications, such as 3D games, for instance, then the primary role will be exactly on the graphics card, as it will be responsible for the spectacular experience the user will get from interacting with the computational algorithms. Most of the articles on our web-site are dedicated to optimization and choosing the best combination of contemporary CPUs and graphics cards. However, processor and graphics card are not the only two components in a contemporary computer system. There are a lot of other parts, which importance shouldn’t be underestimated. However, while we understand perfectly well the practical value of mainboard, hard drive or power supply unit specifications without any additional explanations, then the system memory choice may sometimes become a tricky quest even for experienced users. No, memory capacity is not our concern at this point, things are pretty clear with this parameter. We have long known that the majority of contemporary computer systems can do perfectly fine with as much as 4 GB of RAM: this capacity is quite sufficient for proper work of operating systems, general-purpose applications and last-generation games. Only in certain specific cases you may need more RAM and those users who deal with cases like that are definitely aware of it.
