Game FPS

Ok, I have been preparing to get a Rust key on the dutch auction.
The problem I faced is, what if i can’t run the game on my PC?
Can someone tell me the recommended specs to get 60 FPS (high settings?)
My specs currently are:

Processor: AMD Phenom X4 9150e Quad Core
Ram: 4GB
Hard drive: 500GB
Graphics: NVIDIA GeForce 6150 SE Graphics card.
Windows Vista Home Premium 64bit edition.
Thanks for taking your time and reading/answering!

you are not going to run this game well.
