Yes i think it is still enjoyable to play, with its bugs, the buggy thing is the zombies. The pvp combat and the large areas are very good. Its one of the most detailed and realistic looking map I've seen. And its kinda random how you never know whats going to happen joining big servers with between 20-100 people. Some are armed and hostile and theres lots of vechicles wizzing round,. just shame the zombies are so damn buggy. I guess it would be really good if you had a few friends with Mics and teamed up.
Anyway as for your PC and settings, you can look up games on websites such as 'Can I Run It' and test against your settings. I know in Arma the video settings are very in depth and allow you to turn down individual textures, ground detail, trees, grass, looking draw distance, and many other settings which can increase frame rate or make it go easier on your computer. I guess mainly i would ask what graphics card you have and see if that comes under minimum settings for the game you wish to try. If the game is lagging or sturrering a lot try turning down the video settings, textures ,. Anti -analisaing also uses a lot of power (it blends harsh diagonals and pixels) , i put that on Low on most my games..So i would recomend check out 'can I run it' or a similar website, and tweaking settings down. There is also an Arma II Demo that you could try if you are set on trying it. Edit; here is can i run it:

Shinigami for Goldeneye Left 4 Dead 2. Me and my friend had already done half the map previously but it turned out Really difficult on Advanced and we ended up giving up after so many attempts. Will play some more soon
Also how is the Heist 2 beta game? I saw you have it in your collection and thought about that one too, looks alright
