Review: ROG Ally with a 3080... No complaints here - So, every negative comment I've ever seen about the XG mobile with the ROG Ally was pretty much false for me with one exception. The fan is loud under full load but my sound is usually set louder. I don't understand the negatives here. I even tried to break it and see what the problem is. It docks and undocks just fine. It's ridiculously powerful. I have the desktop version and I honestly am 2nd guessing even owning a desktop right now. Granted, I'm playing at 1080p on a mobile monitor but the FPS is perfect for pretty much all modern games on ultra. I'm using an SSD on USB as extra storage for games and it works fast as expected. I thought I'd be pissed about no USB C but the version of USB A is still plenty fast for SSD gaming. I am returning this one from desertcart because I bought one direct from Asus shortly after for much cheaper. I don't understand why they're so much higher on desertcart. Be patient and pay MSRP through Asus. The 6850 should be $799 and the 3080 should be $1099. Just create an Asus account and click notify on the product. They'll email you when in stock. Lastly, I saw complaints about the pcie X4 vs x8 speeds blah blah blah. Supposedly there's lag with keyboard and mouse. Total bs. I don't know what speeds they are but my FPS are typically around 90-100 on CoD and I have no lag on my keyboard and mouse. It plays like a desktop PC. I'm using all ROG gear for my setup down to the mousepad. I average around 60 FPS on CP2077 with the RT Ultra preset @ 1080p. That's hella good for a modular mobile gaming setup. Review: Super expensive but better than universal egpu - I combined this with the i5 z13 asus gaming tablet and it works very well. I compare it to an amd gpu I combined with razer core x egpu, and I think the asus proprietary system is better performance and more stable. I was debating keeping it because it's so expensive but decided to keep it since I got my gaming tablet pc for cheaper on woot.com. Pros: - very compact laptop ver 3080. Easy to transport as needed in luggage or a backpack. - doubles as a pc dock has everything i want except usb c. - proprietary connection is better performance and stability than other universal egpu in my experience. - easy to upgrade drivers with Nvidia software. Cons: - so freaking expensive def wait for desertcart sales. - fan gets super loud in full turbo mode. Headphones is almost a must. - temper your expectations. It can't run everything at 4k 60fps ultra settings. On a samsung HDTV I typically have to set 1440p 60fps with Nvidia frame generation with older aaa titles like last of us, red dead reception 2, cod modern warfare etc. Works well for 2k gaming. I can get 75+ fps ultra setting at 1080p but prefer higher 2k res vs more frames. - I think they're discontinuing the proprietary connection? The newer refreshed asus z1 extreme handheld gaming pc ditched it for usb 4 c connection. If true then this and the 4090 version should be cheaper!

Smh! ### ⭐ Doesn't really make a difference, very unstable. *by M***N on June 20, 2023* I have the ROG Z-13 with the i7 and 3050, and the 3080 doesn't really do much for gaming. It does however de-stabilize your system and cause about 10x as many crashes as without. Really disappointed. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/505708959-rog-xg-mobile-external-gpu-dock-nvidia-geforce-rtx-3080](https://www.desertcart.co.uk/products/505708959-rog-xg-mobile-external-gpu-dock-nvidia-geforce-rtx-3080) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
