Pros & Cons
👍 Pros
- i7-11700's 8-core / 16-thread architecture at up to 4.9 GHz boost handles simultaneous gaming and streaming without frame rate compromise.
- 512GB PCIe NVMe SSD delivers sequential read speeds that eliminate load-screen waits and keep the OS responsive under multitasking load.
- 16GB DDR4 DIMM (standard desktop form factor) is straightforward to expand — add a second kit for 32GB without replacing existing modules.
- 2TB HDD provides large-capacity secondary storage that extends the SSD's active library without requiring external drives.
- Wi-Fi 6 (802.11ax) and Bluetooth 5.2 represent current-generation wireless standards that won't bottleneck online gaming or peripheral latency.
👎 Cons
- GTX 1660 Super lacks dedicated RT cores, making it incompatible with ray tracing features in modern titles without severe performance penalties.
- 650W PSU is tight for mid-to-high tier GPU upgrades — a GPU swap to RTX 3080 class or better will likely require a concurrent PSU replacement.
- No optical drive included, which matters for disc-based legacy software or media libraries.
- Windows 10 Pro on gaming hardware is appropriate for dual-use setups but adds no gaming-specific benefit — a Home license would have reduced cost with no gameplay impact.
- The included USB hub accessory is a third-party add-on, not a Lenovo-branded component — build quality and driver support are not covered under the primary warranty.
Frequently Asked Questions
What does the i7-11700's 8-core, 16-thread configuration mean for gaming versus productivity workloads?
The i7-11700 at 2.5 GHz base / 4.9 GHz boost gives you strong single-thread performance for gaming frame rates alongside genuine multi-core throughput for streaming, video encoding, and background tasks simultaneously. The 16MB L3 cache reduces memory latency on large data sets. It's a capable production chip that doesn't force you to choose between gaming and content creation.
Is the GTX 1660 Super still a viable GPU for modern gaming?
The GTX 1660 Super with 6GB GDDR6 handles 1080p gaming at medium-to-high settings in most current titles at 60+ fps. It lacks ray tracing hardware, so RT-enabled titles will require quality trade-offs. At 1440p, frame rates drop meaningfully in demanding games. For 1080p-focused gaming, it remains a productive card — but it is not a path to 4K or high-refresh 1440p play.
What bottleneck does the 512GB NVMe SSD + 2TB HDD storage combo solve?
The NVMe SSD eliminates storage as a system bottleneck for the OS, active game library, and applications — delivering sequential read speeds that are 4–6x faster than a SATA SSD and 20x+ faster than a spinning drive. The 2TB HDD provides high-capacity secondary storage for media, archives, and game backups at mechanical drive cost. This two-tier approach is the correct engineering trade-off for a gaming system at this price.
Does the 650W power supply provide headroom for GPU upgrades?
650W is the minimum recommended for an i7 + GTX 1660 Super configuration, with modest headroom. Upgrading to a higher-TDP GPU — such as an RTX 3070 or RX 6700 XT — would consume most of that margin. A GPU upgrade to RTX 3080 class or above would require a PSU replacement. Factor that cost into any upgrade planning.
Is 16GB DDR4 DIMM (non-SO-DIMM) expandable in this tower?
Yes. The Legion Tower 5i uses standard DDR4 DIMM slots, not SO-DIMM. Most configurations have 2–4 slots, meaning the 16GB (likely 2x8GB in dual-channel) can be expanded to 32GB or 64GB by adding or replacing modules — a straightforward upgrade that directly benefits content creation, streaming, and future game memory requirements.
