The Eight of Wands shows that your current situation is characterized by a certain instability. It could be that you are still evaluating the different options regarding your new computer or that you have already decided but are not sure which choice to make. This arcanum also indicates that there is a sense of urgency, as if you feel the need to make a decision quickly.
The reversed Knight of Swords speaks of an obstacle in your quest. It could be something on a practical level such as lack of budget, or something more subtle such as uncertainty about the right path to take. In any case, this arcanum suggests that you need more clarity and understanding before making a final decision.
Finally, Temperance speaks of balance and harmony. This arcanum suggests that you need to find a compromise between the different options available, so that you don't have to give up something but at the same time avoid overspending.
In conclusion, the tarot seems to suggest that you opt for a high-end model over a high-end computer. This is in line with the idea of balance expressed by the arcanum Temperance: a high-end model is less expensive than a completely new computer, but still offers superior features and performance compared to cheaper ones. Furthermore, having already established the current situation and any obstacles with the first two arcana, the last arcana seems to suggest that you can find the right compromise between the various options available.
