Well, I do know that those games are pretty demanding graphically, but I would agree with you that your card should be more than enough to handle them at 1024x768. How big of a "hiccup" are we talking here? if it's massive slowdown, I would say you probably have a driver problem or something, but if it's just not ultra smooth, I wouldn't worry about it, even on high end hardware, graphics-intensive games are bound to hiccup now and then. Then again, I am fairly tolerant framerate-wise, you may lean otherwise. I would check your driver version/any driver documentation to see if it mentions these titles specifically. Also, I know certain titles have problems/don't perform as well with ATI cards (diff. architecture), this may be one of them, I would check online for a patch. Well, I hope this helps you.
