Can someone please tell me why my cpu is running at 90% while im playing cox

probably because it's a game and it uses as many processing cycles as it can possibly use.
Okay, I know that's a smart alec response, and I know what you are getting at. You are thinking something along the lines of... "hey, I have a dual-core Socket AM3 processor from AMD with a high clock speed, loads of ram, and pretty powerful graphics card... surely this thing is going to be fast enough to play my graphics intensive 3D game, burn a DVD movie, rip my audio CD's to FLAC, and print out my 500 page essay on the living habits of the South American BotFly... all at the same time."
Well, the reality is... modern computer operating system's don't quite... operate like that. Most applications applications are, in general, not given fixed limitations on how many resources they can take up, or how many resources they use. Most applications will automatically use every bit of resources that is available to them, and simply leave the sorting out of those resources to the Operating System.
If you really are interested in the theory and implementation of how an Operating System and applications handle available resources, head over to http://www.kerneltrap.org/ and do a search for scheduler: http://www.kerneltrap.org/search/node/scheduler
You are pretty much looking for emails involving Con-(man) Kolivas, and his interactions with other Linux Kernel maintainers like Andrew Morton, Alan Cox, and Ingo Molnar over the Completely Fair Scheduler... and then more recent discussions about this topic can be found at http://lkml.org/ when looking up the BF-scheduler. And yes, I know what BF stands for. It's also why I have more respect for Jack Emmert than I do Con Kolivas.
You'd also want to look into assigning processing priority: again, the theory and implementation of processing priority can be found by looking up the *nix nice / renice
***
If you aren't really interested in the details on why a single application can take up so much of a processors reported power output... here's the short version:
Microsoft has been on a slow process to emulate a *nix type operating system with it's WinNT operating system for several years now. Among the improvements to the WinNT 6 kernel systems are changes that allow programs to better utilize available resources.
Games, at least under the latest updates to WinNT 6, are automatically given a higher processing priority by the WIndows system, allowing the game to take up more of the available resources.
What this means is that City of Heroes is taking up 90% of your processing power because it can take up 90% of your processing power.
Or if you want the simpler version
Vista introduced a change in the way the OS allocated processor usage such that the OS will attempt to fully utilise the processor.
Win 7 being based in the Vista codebase does this also.
Win XP does not.

thanks for the quick info i know jack about pcs i had some wild notion that maybe the game was using only one side of the cpu or sumthim

Nope! COH likes CPU's and can use at least two cores (can it use more? I dunno). So, really, what you've got here is ideal - the game is using your nice hardware as best it can. If COH only made use of one of your cores (and many older games will only use one core), then you'd have a whole core sitting still, twiddling its thumbs, and you wouldn't be nearly as happy with the game's performance.|

You can improve your performance by playing with some of the settings. If you type: /showfps 1 then you can see how many frames per second you're running at (type /showfps 0 to make the counter go away). If you think its choppy, then lower settings. If you're running nice and fast, maybe try turning things up and see how pretty you can make things while the framerate still being playable to you.
Enjoy!

No, just two. Although it now uses two by default (if you have them). Previously you had to tell it to use two.
