Hey mate, how do I know if my laptop has an mxm gpu or notYou can't upgrade graphics in most laptops for 3 reasons:
1. Most have soldered graphics chips and hence aren't upgradeable.
2. The cost of mobile graphics is prohibitive. An RTX2080 card is around £1500
3. It's not just a case of updating the graphics, there's also having to include a compatible BIOS to read the new graphics card. These can be very hard to find if at all.
The only chassis that PCS do with an MXM graphics is the Octane.
