Got a question about 360 controller

Lets say i get oblivion to my pc,so i can play with high resolution since i dont have a HDTV,can i use my 360 controller to pc and play it?
Cause i really want to use a handcontroller,and if it works i only need to plug it in in a usb port? or do i must buy something extra?
cause i have a big 19 tft,would be very cool,and the price is half on pc games then xbox/xbox360 in sweden.
And btw,i got a psx emu,yes,i got a psx+ps2 too,but i dont like the saving on saving slots,i like quick save,and memory card broken often,do you think the 360 controller will work there too :PCause they support controllers.
Oh btw i just saved,been playing a lot of cod2 :P
Gonna upload many pic' s,the game kick ass.

Even if you break 2 legs from a crab it still runs!
What you gotta do is find its weak spot and do massive damage at it.

You can use the wired 360 controller as a PC controller.

But im going premium package,do i get any wired in it?

Nope, only the wireless controller. That' s why I' m taking the wireless controller that comes with the premium and getting it exchanged for wired controller. And if I' m only allowed to trade it in for credit I' d rather do that and pay the difference. Still cheaper than paying for a seperate PC and 360 controller when I can just have two in one.
