I'm running Half-Life 2 on my grandma's computer (the specs are better then you would assume), and it runs terribly on recommended settings, and even on the lowest settings it never goes above 30 fps. Specs are as follows:
Quad-core Intel Core i5 clocked at 3.2 GHz
Nvidia GeForce 310 (512 GB DDR3 VRAM)
8 GB RAM
Windows 7 Home Premium 64-bit
P.S. It is also notable that "multi-core rendering" or whatever it is, is disabled by default.
P.S.S. Don't ask me why my Grandma needs 8 gigs of RAM
