Building First AI/LLM PC With Dual 9070 XT GPUs – Any ROCm or AMD Issues I Should Know About?
I wanted to build a PC for a long time, but prices always stopped me. Recently I read that prices may not come down anytime soon, so I decided to just build it now.
My main use case will be running local AI models for occasional gaming, some python/go automation coding and research automation. I want to process a lot of PDF and XLS documents using tools like Docling, Granite, and OCR models, then store chunked data in Qdrant/vector DBs.
I am new to this area, but I work as a cloud engineer and I am comfortable setting up technical systems and learning new things quickly.
Right now I am planning this build:
- 2 × 9070 XT GPUs
- Ryzen 9950X CPU
- 64GB 6000MHz RAM
- 1200W PSU
- Proper case and cooling
My main concern is using AMD GPUs instead of NVIDIA because AMD gives more VRAM for the price.
Before I buy everything, I wanted to ask:
- Will this setup work well for local AI workloads?
- Are there any major ROCm or AMD GPU problems I should know about?
- Anything important I should be careful about before building?
Any advice would help.
