it doesnt stress your card because it is made to work with an nvidia card. which is another reason i suggest it. i think ati tool sucks, but thats just my opinion. but then again i could never get past the "bugs". i can also tell you that overclocking your video card is great fun and all, but it really doesn't make a huge difference in games. if you're getting 60-70 fps in a newer game, you aren't going to see a difference (by "see", i mean see during a game).
comparing coolbits to ntune is kinda like comparing apples and oranges.
i will agree that ntune sucks at overclocking. but if you're using it to overclock, you're dumb. not you pepsiboy, i'm speaking figuratively.
