According to the European Comission website:
If you enter the EU from a non-EU country, goods having no commercial character in your personal luggage can be imported free of customs duties, VAT and excise duties within the following limits:
...
Other goods (including perfume, coffee, tea, electronic devices etc.)
Up to a value of €430 for air and sea travellers
Up to value of €300 for other travellers
- The value on an individual item may not be split up.
- The value of personal luggage (i.e. suitcases) and medicinal products for the personal needs of the traveller do not count.
- Member States may reduce the above limits to € 150 for travellers under 15 years.
Therefore the answer is that yes, you can import a graphics card tax-free into any EU country, as long as the total sum of imported products doesn't exceed 430 euros. Note that products previously purchased in the EU (e.g. clothing and other electronic devices) don't count as an import.
