I have a computer with 3 PCIE x1 slots and I am thinking of buying such an adapter. But will it affect the performance of the graphics card?

It doesn't work that way. If you want to add another graphics card, you will have to invest in a new motherboard with the the extra PCI express x 16 slots.

Yes the adapter will severely bottleneck a modern performance GPU since the speed will still be X1.

Unless your bit mining or something like that you will be bottlenecked.

First 2 answers partially true.
Such adapter isn't proper solution for various reasons :
- possibly not enough power supply from the slot,
- performance would be drastically lowered due to latency and slot throughput limitation
- for CF or SLI you need support from the chipset also... so you wont boost your gaming performance this way

Btw as one of above answer suggest you need mobo with extra x16 slot, is partially true... I've seen mobos with another slot but without SLI/CF support... so the correct answer would be you need a mobo with such support AND with additional x16 slot.
Another thing is that to boost performance in SLI/CF you need in most cases the same model of the GPU you already have... and most likelly you need such card to support SLI/CF as well (depending on external/internal bridging)

The only reason to put a card this way would be some processes like bitcoin mining (or other kind math processing) where u don't need CF/SLI since all cards can work solo.
