Hi people, these two cards, HIS 7950 IceQ Boost and Sapphire HD 7950 with Boost, are currently on sales and I would like to know which of these two is better, in terms of performance and reliability, before the sales end! I have read from a review that HIS card is quieter and cooler, but the two cards mentioned in the review are different from the ones I'm currently comparing. Any input will be greatly appreciated!
