This is just a general question that I've been wondering about for a while. When buying a video card is there a quality difference between different sub-videocard brands such as PNY, EVGA, XFX etc. The reason I ask, is that back in the day when I was still new to computer modding/upgrading, I bought a Diamond radeon 128mb vid card. In theory it should have supported at least simple games such as warcraft 3, but whenever I ran any gpu intensive program it crashed.
