| I love the performance of my Intel i7-10510U processor with 12 GB RAM. The NVIDIA GeForce MX250 graphics card allows for some gaming, while the 1000 GB SSD provides ample storage. The 14-inch IPS display with Full HD resolution is vibrant and perfect for watching movies or YouTube. Overall, a great laptop for both work and entertainment. | ||
