I was planning to buy the Evga gtx 750ti from Amazon because it's cheaper in Canada but I found out that there's amsuperclocked version for 10$ more, they both say 300e minimum psu and I have a 300w psu but how could an overclocked version have the same power consumption that the normal one? Should I get the superclocked version wich has a base clock of about 100mhz more and a boost clock of 200mhz more than the normal version?Will I be able to power it? I'm a really bad overclocker so I can't put the normal one upto those frequencys.
