Problems can arise with all cards. Sometimes you can't go by the Newegg reviews. Often only the folks with an axe to grind will respond. I've had two HIS cards with no problems. In fact, I can't think of any gfx card I've had that ever failed. So... you take a chance with any card. Personally, I'd jump on the extra performance of the 270 for that price.
Can you link me to the HIS card is question?
