"capped it on 60fps in the config file" might be the problem. Does that mean you turned on v-sync? If you can't reach 60 FPS with V-sync turned on then the FPS is halved I think.
But you also only have 4GB RAM. 8Gb is recommended for gaming.
Your GFX card is a m-version of a GT 650. It's not a high-end GFX card. And Bf4 is a high-end game. Oh and it only has 1GB om Vram. That could be a bottleneck.

I think the "minimum requirements" are for playing the single-player campaign. Multiplayer is more load on the CPU.
