Radeon R9 380 or GTX970 for HP 8570p

[Edward09]

Hello everyone,

I am a newbie in this forum and I've known about eGpu for just a few days. So i want to ask you some questions. I have an HP Elitebook 8570p and this is my specs : 

 Intel core i5-3320m

 VGA: AMD HD 7570m

I am planning to use an EXP GDC beast 8.0 and there are 2 options i am wondering : radeon r9 380 and gtx 970. I like r9 380 more because it's cheaper, but someone says it's hard to set up an AMD card for a laptop which also have AMD dGPU . IN the other hand,a GTx is easier to set up and have better performance. SO which one should i buy ?

Another question : As I know a core I5 CPU always have integrated card Intel HD 4000 on it, but when I check in the device manager there's only dGPU Radeon 7570m. Is it possible for me to use an EGPU?

Sorry for my English . Please help me and thanks in advance
