Oh, this could be fun. I'll post both of the machines I use regularly.
Desktop:
i7 4770K
16GB 2133MHz RAM
GTX 770 2GB VRAM
240GB Â Samsung Evo Pro 840
Laptop:
i7 4702HQ
8GB RAM
GTX 870M
128GB SSD
In terms of graphics, the HD4200/4400 iGPUs perform well enough to run the game and have it look like the PS3 (PS3 probably gets more effects though). I've used one of the more recent intel NUC boxes for emergency gaming before. (Raiding is impossible on them though). The HD4600 or the higher-end 5000 series would probably be good enough for things not overly intensive.
