Unsurprisingly, board makers have jumped on the opportunity to serve up customized, higher-clocked versions of the Radeon HD 7870 and Radeon HD 7850. Those settings yielded substantial performance gains without huge increases in power consumption. We were able to overclock its memory from 1200MHz to 1375MHz, as well. Our reference Radeon HD 7870, which came to us directly from AMD, had no trouble climbing from its stock 1000MHz clock speed all the way up to a blistering 1275MHz. One of those advantages is a rather substantial amount of overclocking headroom. The new Radeons therefore have to play up their other advantages in order to seduce prospective buyers. In a nutshell, the 7800-series Radeons deliver only slightly better performance per dollar than the prior-gen Radeon HD 6900 cards, though they have the potential to be much cheaper. Nvidia charges a pretty penny for its freshly released GeForce GTX 680, too, which has a smaller GPU and the same memory interface width as the GeForce GTX 560 Ti yet sells for twice as much. Whispers around the industry suggest the higher prices can be attributed the limited supply of 28-nm wafers coming from TSMC, the Taiwanese foundry that manufactures chips for AMD, Nvidia, and other firms like Qualcomm.

Unfortunately for bargain hunters, AMD has priced the Radeon HD 78 at $249 and $349, respectively, well above the $180-240 price range the 6800 series occupied when it arrived in October 2010. Thanks to a new 28-nm chip fabrication process and a revised graphics architecture, dubbed GCN, they even outpace the old Radeon HD 6900 series cards, which are based on larger chips. The newcomers are quite a bit faster, too. In that initial encounter, we learned that these cards have all the makings of successors to the popular Radeon HD 6800 series: similar-sized GPUs and memory interfaces, with lower power requirements. We studied them, and the Pitcairn graphics processors that dwell within them, about three weeks ago. I do not open the case, but I did remove the extra metal thing that was covering a PCI slot for a little bit more air.We’re already well acquainted with AMD’s Radeon HD 78 graphics cards.

I just want to make sure I'm not cooking/damaging the other things inside, and what else I can do to lower the temperature. However, with this new 6870 I do notice sharper, crisper image quality. Unfortunately I did not measure any temperatures when I was using that GPU. I'm still using the same settings as I was when I was using the Radeon HD 7570, which was high setting. Well one of the games I play is Lineage2, and when I play it the temperature readings for the GPU get up to 85*C.

I also have SpeedyFan installed to see the temps of the other stuff. I installed MSI Afterburner to see how hot this thing gets after I notice the case got fairly hot, I also now use it to control the fan have it set to 90% when it reache 80*C, and 100% at 90*C. I figured if the Radeon HD 6850 and Radeon HD 7950 were valid options during the customizable process that it can probably handle a Radeon HD 6870. And now I have the big loud XFX RADEON HD 6870, non-reference single fan version.

So I upgraded the PSU to a CORSAIR HX650W. I have the HP Pavillion HPE h8-1240t, with the i7-3770 processor and it did come with the fairly good and very quiet Radeon HD 7570.
