Does any one knoe the fastest/most stable settings are for overclockin on this card? Yesterday, I was able to get it from 275 core/550 memory to 315/600. I didnt wanna go too high. This is my first time o'cing a video card and i didnt wanna f it up... btw, i just bought it.. cause HALo came out..... . .. . Im getting about 32-36 fps avg in HALO at 1024x768 on my 2.1 XP 2400+... but should I return it?... and get the 5700 ultra or the 9600XT? ALL I KNOW IS, I SHOULD HAVE WAITED.... thanx in advance.
