If you’re in the market for the biggest and baddest mobile desktop replacement at a not-so-otherworldy price, then check out this week’s Best Buy deal. Right now you can pick up the Acer Predator Helios 18 gaming laptop equipped with an 18″ display and RTX 5090 GPU for $3,499.99 with free shipping after a $1,000 instant discount.
There aren’t very many 18″ gaming laptops around, and even fewer that are equipped with the RTX 5090 mobile GPU. Of the ones that are available for purchase at the moment, this is currently the least expensive deal. In fact, this is the only model I’ve found with a price tag under $4,000. Take a look at its competition (and note some of these are sale prices):

The Predator Helios is Acer’s highest end 18″ gaming laptop and you’d be hard pressed to find anything (portable) that can beat it in gaming performance. The 18″ Mini-LED display boasts a 3840×2400 (252ppi) resolution with 240Hz refresh rate, G-Sync support, and 1,000 nits of max brightness. The system is equipped with an Intel Core Ultra 9 275HX processor, GeForce RTX 5090 24GB mobile GPU, 32GB of DDR5 RAM, and a 2TB SSD. Since this is a newer 2025 model, it also supports the Wi-Fi 7 and Bluetooth 5.4 standards and has Thunderbolt 5 ports.
The GeForce RTX 5090 is without doubt the fastest mobile GPU you can get
The Nvidia GeForce RTX 5090 is the most powerful mobile graphics card on the market, performing about 15% better than the RTX 5080. It also has more VRAM (24GB vs 16GB), which can come in handy when playing games at higher resolutions (like on an attached 4K monitor) or if you’re planning to use this as a mobile creator or AI workstation. This is the only mobile GPU currently available that can run most games at 60+fps on the laptop’s greater-than-4K resolution display.
It’s important to note that, in most cases, a laptop GPU is not a direct 1:1 performance comparison to its desktop variant. For example, a mobile RTX 5090 is not as powerful as a desktop RTX 5090. Instead, a mobile RTX 5090 is more comparable in performance to a desktop RTX 5070 Ti. If you think about it, that makes sense because the mobile RTX 5090 has a TGP of 150W compared to a whopping 575W for the desktop RTX 5090.
