Got my self some krk rokit powered 5 g3 (have had the krk rokit powered 5 g2 just over 1 year, then dali speakers, i now use for my tv and tommorow i would have had my yamaha hs 8 for 7 month, only had to get a new pair of krk g2 and then all of my speakers worked fine) I have a Msi Z77 thunderbolt, i5 3570k, asus hd 7970 Dcuii Top, 2x4 gb skill trident x 2400mhz xcl 10 ram,a seasonic g-650 psu, soundcard presonus 22vsl and a 21:9 2560x1080 monitor. I have some kind of coil whine, high pitched sound from my speakers that i never had before trying to play games, exit the game or turn off the power to my speakers, the sound goes away, only notice it when i want to play games. Using dvi cable, using dp to hdmi cable adapter with a good hdmi cable, change dvi port and i still have something that sounds like coil whine, using my igp i have no high pitched sound,coil whine (but using a i5 3570k for games i can't recommend) My speakers are so new that i can get my money back or exchange them to something else. What would you recommend med to do? If i gonna buy a used gpu (my asus hd 7970 is only a few month old) i wouldn't wanna spend more on what a used gtx 670/760 costs (mabye a second one later) , but they are not as good as a hd 7970 ghz and exchange,sell my card with something that sounds like coil whine (even when it's only with my current speakers i have this problem) i might not be able to get what i want for my hd 7970, wouldn't be fair to sell it without telling about the high pitched sound. Just got skyrim very cheap and want to play it, but i can't because of this anoying high pitched sound What would you recommend me to do? I live in denmark and have bought my gpu from caseking.de, i don't think i can rma it because of age, price is also high sending it to casking with track and trace (with insurence) about 30-40€ , if they can't hear anything i have spend money for nothing, do they send it back to me for free?
