Mantis V2
Is this PC a good deal?
Mantis V2 is a prebuilt gaming PC from amazon with RTX 5090 graphics, Ryzen 9 9950X3D processor, 128GB DDR5 memory, 4TB SSD storage. At $8,249.99, it is listed as in stock. PC Per Dollar estimates similar DIY parts at $6,540, so building it yourself is about $1,710 cheaper. Its PC/$ score is 12.5, with a 100/100 excellent performance rating. Use it as a fast shortlist signal rather than a guarantee: a good score means the hardware package is priced well against current component estimates, while a weak score means the convenience premium is doing more of the work. The retailer page should still be verified before purchase because final price, stock status, shipping, taxes, retailer-specific bundles, and included parts can change after PC Per Dollar last checked the listing.
