I would prefer the HIS the Sapphire doesn't have superior features to back up the $15 price premium (after accounting for MIRs)
Before accounting for MIRs I would choose the Sapphire just because of brand preference really the only difference is that the HIS is cheaper after MIR
You know, if price isn't a factor and you instead want something more powerful for a little extra, then why not go for this? http://www.newegg.com/Product/Product.aspx?Item=N82E168... $139.99 after MIR. More powerful card as well. Only thing I can think of is the minimum power supply requirement, but that spec isn't listed unfortunately.
