este som zabudol dodat ....When it comes to overclocking the PowerColor PCS+ HD4870, I used a piece of software called AMD GPU Clock Tool. The HD4870 was an extremely easy card to overclock; I was able to get it up to 860MHz stable on the core very quickly, and was able to jump around 10MHz every increment. I was able to get it all the way up to 870MHz, however it was unstable and unable to run 3DMark06 all the way through. I feel that if I were to perform a voltmod to the card, I would be able to achieve a higher overclock - maybe near 900MHz. During the overclocking process, the temperatures did not go up more than a few degrees; however, after those few degrees, the final temperature was between 53 to 55°C under a full load. A substatial decrease over the reference cooling solution.

ked ta karta pri 820Mhz "zlobila" tak potom treba pozret ako som sa zmienoval uz vissie na kartu od power color-u konkretne PowerColor HD4870 PCS+ tam sa dostali na 850/1100 stabilne bez problemov a ktomu ta karta mala velmi slusne teploty.

0% narast vykonu??? oproti povodnej to mas namysli 750/3600 gpu/ram oproti 825/1000 gpu/ram tak asi si dost slepy ked nevidis rozdiel oproti referencnej karte.
a co tak otestovat radeona od power coloru ktory ma priaznivejsiu cenu a dosahuje lepsich vysledkov ako toxic do sapphire. ku prikladu http://www.overclockersclub.com/reviews/powercolor_4870pcs/.
