| I have a powerful Intel i7 processor with 8 threads and 4 cores, great for multitasking. The NVIDIA GeForce MX150 graphics card allows for gaming. The 1000 GB HDD is spacious for files. 8 GB RAM is decent, but more would be nice. The Full HD IPS display provides clear and vibrant visuals. Overall, it's suitable for office work, entertainment, and light gaming. | ||
