That's the bare minimum for RAM.
I've got the same card, too, and it's okay. I can run with full models, textures, and shaders in HL2SP, but for performances' sake in multiplay I run with everything low, as it does have the occasional laggy bit. (And CS:S shaders, especially cs_office, fucking EAT FPS ;x
That's about all anyone can tell from the specs, and it's like, teh same as the other thread. Continue your discussions in there.
