I have a alienware x51..I know a lot of the community have issues with this pc due to the power..Including my self..Im running i5-4440 3.10ghz..8gb ram..NVidia gtx 645...240 psu....I contacted Dell and they told me the highest card I could go was a gtx760 without upgrading psu...im curious if this card will work properly and if I could jump into the overclocked version from EVGA running with 2gb on board...Still very new to the pc gaming market but not stupid...lol...just wanna know that this is possible!? thanks
