Okay, I bought a brand new velocity micro pc from best buy. Its an awesome pc and I have overclocked the card to 770mghz. My question is how do you know how many fps you are getting. Everywhere I hear I got crysis on 35 fps or COD 4 at 50 fps. How can you tell? Is there software that can tell you? please help

use Fraps.
Its free, and at its most basic level displays the current fps in the top corner
Crysis does have an option ot show the fps in the corner, mainly cos Crytek knew people would want bragging rights, most games dont include this.

Frpas can also record small sections of video( though you need the paid for version to get decent footage)
