EVGA GTX 970 Help !

[cool3r]

Hello everyone, I have a problem that I would like to discuss with someone that is good with graphic cards.
I currently have R9 270X Sapphire Dual X, and I'm looking in buying a EVGA GTX 970 4GB, I found it for 100Euros, and that good for me, but, the buyer says that he cant install drivers correctly, he didn't try anything, and I'm thinking to buy it, and fix the driver issue by installing clean windows 10 enterprise
64bit, so tell me, should I stay with the working R9 270X, or should I risk and sell my R9 270X and buy GTX 970.
PS. I hate AMD Cards, but I live in a poor country so it's kinda expensive for me to buy NVidia, and sorry for my bad English...

It's always a gamble. Back in ye olde days I bought a Geforce4 Ti 4600 from eBay with a similar problem and nothing I tried would work including flashing new firmware to the card. It just would not correctly recognise in Windows.

Ask yourself how much that 100 Euros means to you and whether it might be better to save a little bit more and buy a fully working GTX 970
