Kompanija PowerColor svima je poznata po svojim modelima grafičkih karti. Svakako jedan od glavnih aduta je i overklok potencijal, koji je jedan od bitnih faktora pri kupovini, bar kada je naša zajednica u pitanju. Ovom prilikom SXT je u saradnji sa WinWin IMMO centrom organizovao akciju kojom će svi članovi SXT-a biti u mogućnosti da od utorka (18.novembra) dođu do svog primerka toliko hvaljene PowerColor ATI 4870 grafičke karte po veoma povoljnoj ceni.

Jedan od presudnih faktora kod overkloka grafičkih karti jeste i hlađenje koje poseduje. Današnji akceleratori zbog svoje i suviše kompleksne arhitekture, otpuštaju veliku količinu toplote, pa samim tim i inženjeri koji projektuju hlađenja imaju dosta muke oko izrade istih. Da priča bude još gora, bolje hlađenje povlači i konačnu cenu proizvoda, što nikako nije povoljno po krajnjeg korisnika. Međutim, ne mora da bude tako ako ste član SXT zajednice i ako za dat novac želite isključivo maksimum. Naime, da se vratimo na priču iz uvodnog dela ove vesti.

WinWin IMMO Centar u saradnji sa SXT-om organizovao je akciju u kojoj je dovoljno da od utoraka (18.novembrar) odete u pomenuti centar i da se pozovete na SXT akciju koju promoviše ova vest. Ljubazno osoblje će vam uručiti jednu (ili pak koliko vam je neophodno) grafičku kartu oznake ATI Radeon PCS+ 4870 PowerColor PCI-E 512MB/DDR5/TV-Out/DVI/fan/256bit po ceni od samo 201 euro (najpovoljnija cena po kojoj može da se kupi pomenuti model bilo gde). Moramo da napomenemo da se ne radi o akceleratoru sa referentnim hlađenjem, nego o modelu sa dosta boljim hlađenjem, i samim tim većim overklok potencijalom. U koliko postanete ponosni vlasnik ovog modela, SXT vas poziva na forum, kako bi preneli svoja iskustva vezana za ovu overklok „zverčicu“!
