Is your computer tough enough to go toe to toe with the world warriors of Street Fighter IV? Capcom's official recommended PC specs hold the answer.
As you can imagine, rendering frantic fighting action isn't a job for a low-end PC. According to Capcom, you're going to need at least an Intel Pentium 4 2.0GHz or better processor to get the job done, with at least 1GB of RAM and a Shader 3.0 compatible video card with at least 256MB of video ram. Those are the minimum specs, so I'd imagine the game won't look all that great running something like that.
Now an Intel Core2Duo with 2GB of RAM and a video card with 512MB of VRAM? That's much more like it.
Check out the full recommended spec listing below, though you might want to ignore that last bit under the minimum section. You do not want to play Street Fighter IV with a mouse and keyboard.
