Is a mini pcie egpu worth it?
My laptop has an i7-3740qm and 8gb DDR3L Corsair Vengeance Ram, I would like to know if an eGPU setup is worth it I was thinking about using a GTX 970 but have also considered using low power consumption cards such as a 45w RX560. I am just wanting to know about how much bottleneck the mini PCIe causes/ how close to desktop performance. Also what cards would be best if you guys think that this setup is, in fact, worth it.
Pending: Add my system information and expected eGPU configuration to my signature to give context to my posts
Since the cost of a mPCIe setup is very low (you can get an adapter for 7$, a 20$ power supply and any card you choose) it is rare that it is not worth it. It is typically not worth it if you try to use a very powerful video card on a low resolution monitor, where you'll hit diminishing returns pretty fast due to the single PCIe lane.
If you run a single external monitor at 1080p or lower, then something like a RX 480 (can be found used for under 100$) is likely a good investment.
