Answer:
1. Intel CPUs with processor name K or X (K or X series)
2. Motherboard and cooler
Explanation:
1. If Maggie wants an Intel CPU that she intends to overclock the CPU the the best way for her to indentify which intel CPUs are capable of overclocking is to look out for Intel's CPU processor with a K or X chip.
2. Maggie will need a Mother board with a socket that's compatible with the Intel's CPU K or X series. Another component Maggie will need with overclocking in mind is a better cooler to better manage the temperature. The temperature increases when you boost the clock speed. Having this in mind, one will need to upgrade the cooler to keep the temperature level low.
