I've set my mind on getting a 7870 but my friend's been telling me to get one by HIS except I've chosen an ASUS one. I don't care about the prices, I care about which performs better. Yes, I plan to overclock. Halp neded, thank you.
If you plan to overclock, then I would probably stick with the ASUS.
I like the unique design on the HIS but I'd get ASUS because, it's ASUS.
Also the ASUS 7870 has dual fans for cooling and many more people use it so if you ever have driver problems or want to do something with it, there will be a larger variety of people to ask.
I have heard negative about blower fans, yet positive about asus.
