Vista - Best Vista Game

I am a massive online gaming fan. Well I used to be. I've not been online since tribes vengeance came out, so I'm way behind you all now lol.

I'm looking to start gaming again but I have no idea of what games are compatible with vista. The games I used to enjoy, where S.O.F, Tribes Vengeance, Halo, Far Cry and Need For Speed. I love online gaming/ Multiplayer.

Are there any games like these out now? What would you recomend? what do you think is the best game out there so far?

I have a few games installed at the moment, most of them work without any problems at all. (ATI GPU)

works fine:
Crysis, Doom 3, Dawn of War, Duke nukem, Elite force (1 and 2), Ragnarok Online, Gunmetal, Halo, Metal Gear Solid PC, Oni, Steam (and 7 steam games),

has issues:
Supreme Comender, Ragnarok Online 2, Metal Gear Solid 2 PC.

I've had no problems with Call of Duty 4, using Vista Home premium 64 bit, and Half Life 2 The Orange Box.

Bioshock is a damn good game. i run it with no issues.

Games I run with no problem: I am running vista x64
World of Warcraft
Timeshift (this game is beautiful)
Hellgate London
Shadowrun ( if you like a new take on counterstrike, this game is crazy, you can teleport through walls)

some of the games which work on my computer

All the dx9 games (plus Bioshock and UT3 in dx10) run at 60 fps. Only Crysis is running at below 40 fps but that's because I have it set at the highest dx10 settings.

I'll post my specs later, vista rating can be seen in the rig.

Just a note to all about computer specs,
If you edit your signature to include your system specs then they will be displayed every time you post. This can be handy if you are posting a problem as we can see your specs without any intervention from yourselves.

done.

Added review links for most of my hardware in case anyone was curious. Not advertising, hehe.

I know this might be a stupid question to most guys in here, but how do I find out my specs?

A simple place to find basic specs is under Control Panel/system/Device Manager. might want to familurize yourself with things in here as if there are hardware/driver problems in the future (trust me there always are) then this is a good spot to start. For now you need only to list what you see in others post on here.

Also World in Conflict multilayer is like electronic crack to me.
