My laptop has a better processor than my desktop, its a core i7-3520m 2.9ghz. The laptop has 16GB of RAM and im thinking about using this, https://www.banggood.com/Expresscard-Version-V8_0-EXP-GDC-Beast-Laptop-External-Independent-Video-Card-Dock-p-1009976.html?p=QZ080112991202201708&stayold=1&cur_warehouse=USA, in order to run my 1050ti as an external graphics card. So my question is will this work?

    No, I don't think so. The link you posted, the first line says NOT compatible with GTX 1050 Ti. And laptops are notoriously bad for Rift compatibility. 
    AMD Ryzen 7 1800X | MSI X370 Titanium | G.Skill 16GB DDR4 3200 | EVGA SuperNOVA 1000 | Corsair Hydro H110i

    Yes - the rift can work on a egpu but not the solution you suggest. I'm running the Rift on a Thinkpad P51 combined with a Sonnet Breakaway eGpu (gtx1080) using a Thunderbolt3 connection. All works fine.
    The expresscard solution you posted is waay too slow for VR.Thunderbolt 3 is what you would need in your laptop. Also, I'm not sure but is the i7-3520M supported? M=mobile=less powerful if I'm not mistaken. I'm not sure if it would meet the minimal cpu spec for the rift.

    The oculus rift recommended cpu is the i5-4590
    on cpu boss, the cpu compare sight, the i5 scored 8.2 and the i7 3520m scored a 8.1. http://cpuboss.com/cpus/Intel-Core-i7-3520M-vs-Intel-Core-i5-4590, the Sonnet Breakaway eGpu is a little much for me unfortunately. Is their a cheaper option out there? because at that price i might as well switch my dektop PC from its core i7-920 to a newer AMD processor and motherboard.

    Technically Yes, it'll work but just like maxBr mentioned above you'll need to set it up on a Thunderbolt 3 connection. And if you're looking for more better options of external GPUs that are desgined with VR in mind then view these. Good luck.
