Please note that upgrading to a more power-hungry GPU requires a better PSU. However, in most cases, this may not be possible because most OEM pre-built PCs have motherboards that use a proprietary power connector. Nevertheless, this problem can be solved by using a power adapter. The more challenging problem arises when the model has a non-standard chassis or power supply, in which case upgrading the PSU becomes much harder.
The Dell XPS 8940 supports Gen10 Intel Core technology. Intel released its 10th generation of Intel Core processors in 2019. This update is more significant to the company's lineup than previous generations. This is because the 10th generation is using 10nm manufacturing process. The new technology brings more energy efficient CPUs which is especially important for mobile devices.

Ports are important and often people don't think about them when buying a PC. For example, if you don't have enough USB ports, using external devices becomes problematic. Before you buy any system, considering your use case, check the number of external devices you are going to use and plan the number of the extension ports accordingly.
The Dell XPS 8940 comes with ten USB ports in total. Having more USB ports is always better, but also pay attention to the version of those USB ports. Higher version ports support faster transfer speeds. It is nice to see that the model has a USB 3.1 port. This interface is using 10Gb/s connection and it's very useful when you transfer big files to external drives.
The DisplayPort (DP) is the most widely used digital interface for transmitting digital video and audio between display devices and PCs. It is good to see that the Dell XPS 8940 is featuring a DisplayPort 1.4. The post version is important if you target higher resolutions with high refresh rate. Although, ver. 1.2 is completely fine for most users, if possible, aim for the higher versions DisplayPort.
The HDMI port is another digital video port you can use to connect external display. It has very similar capabilities to the DisplayPort with few exceptions. Dell XPS 8940 comes with one HDMI 2 port(s) on the motherboard. In case your monitor supports another interface, you can always use an adapter.
*Please keep in mind in order to use the video ports available through the motherboard, you need a CPU with integrated graphics card. If you have a dedicated GPU, use his ports instead.
SSD storage - M.2 sockets and SATA ports
The SATA port is one of the places where you can connect a stora gedevice. The Dell XPS 8940 comes with three SATA port(s). Not enough SATA ports might limit your options for additional storage devices. Think about your use case and decide if the SATA ports provided by this model will be sufficient.
Dell XPS 8940 has also one M.2 socket(s) that supports both PCIe NVMe (PCIe 3.0 x4) and SATA M.2 drives with speed of up to 4 GB/s. This configuration works very well for both gaming and work related tasks.
The M.2 PCIe SSD connector in combination with an NVMe drive allows for higher transfer rates, compared to the old SATA interface. In some situations, NVMe device connected to the M.2 PCIe socket can be more than 5 times faster.
