Can it run modern games at 1080p?

Yes, but with limits. Esports titles and older games run at high settings and frame rates; the newest AAA games need medium or low settings to stay smooth on the RTX 3050 6GB.

Is the Core i7 a current-generation CPU?

No. It is an older-generation part, and the DDR3 memory listed confirms a dated platform. It handles everyday tasks and most games fine, but it trails modern budget CPUs.

Can I upgrade the graphics card later?

Physically yes, but the basic power supply and case may not support a larger card. Check the PSU wattage and connectors before buying a replacement GPU.

What storage does it have?

A 512GB SSD for Windows and games plus a mechanical hard drive for extra storage. The SSD keeps boot and load times fast; the hard drive is slower for large game installs.

Does it come with Windows installed?

Yes, Windows comes preinstalled, so it boots to the desktop on first start. Expect to run Windows Update and GPU driver updates before gaming.

Is it good for streaming?

Light streaming is fine, since the RTX 3050 has NVENC encoding and 16GB of RAM covers a game plus streaming software. Heavy multitasking or high-bitrate streaming will strain the older CPU.
