I'm inclined to say yes; it should work in your rig no problem.
Drivers are not nation specific so I don't see why the GPU it's self would be. The only problem I can foresee is if you plan to hook it up to a TV which is PAL, vs NTSC. And even then I think the GPU/drivers would auto detect and change the out put.
NTSC is the video system or standard used in North America and most of South America. In NTSC, 30 frames are transmitted each second. Each frame is made up of 525 individual scan lines.
PAL is the predominant video system or standard mostly used overseas. In PAL, 25 frames are transmitted each second. Each frame is made up of 625 individual scan lines.
