Our verdict

Dell Precision 3660 Tower Computer is our pick.

For any GPU-accelerated workstation task in 2026 — CAD, 3D, GPU rendering, or local AI inference — the Dell Precision 7780 wins because its RTX 3500 Ada (12 GB GDDR6, Ada Lovelace) is one to two generations and several tiers ahead of the 3660's entry-level Quadro T1000 (8 GB GDDR6, Turing); the 3660 only pulls ahead when you need its 64 GB RAM, 2 TB storage, and desktop expandability over the laptop's 32 GB and 1 TB.
