Actually I just got today the HIS HD 4870 1GB, the one with the blue PCB and a big GPU heatsink. It really works great. I OCed it at 675 and temps are 40C Idle and and 68C Full load. Fan is really quiet.
I love it
I am waiting for prices to drop and I'll get one more of the same HD4870 so I can crossfire it.
I'd say any brand that has an upgraded cooler. They do get pretty hot and you want a cool cooler. I have an Asus w/ Dark Night cooler. I love it, however at idle the fan sits at 50%, which is a little loud for me. However my PC is pretty quiet by itself, I just made a fan profile in Rivatuner and took care of that. However the Sapphire has a nice big cooler and HIS has the ICEQ cooler.
For some reason the 4870's 512 have skyrocketed in price, not sure why because AMD supposedly dropped them by $50 last week.
The best brand is the one with the best warranty.
