|If your system supports SATA, that's what you should get. I suggest you go bigger than 160GB though as larger drives are generally faster & don't cost much more. How about a single platter 320GB or 500GB drive? And make sure it has at least a 16MB buffer (more = better) & spins at 7200RPM. Avoid "green" drives if you want the best peformance.|
As for gaming, the HDD performance is only a small part of what it takes for a decent gaming experience. Make sure you have at least 4GB RAM & a good gaming video card, not onboard graphics.
