The hd 7770, Gtx 650 and gtx 650 ti seem to be good competitors the 650 ti even seems to be a nice small jump in performance upgrade but i am still unsure what to get to get the best money-performance-power ratio. My current setup uses 220 - 230watt at load and i want to go to 180-200watt (and to 150 watt when im getting a i3 t processor or underclock). I heard the reference 650ti uses 110watts and MSI's 650ti uses only 80 watts and the reference 7770 uses 90 watts but the tomshw chart seems to think different about it. im kinda lost here.
Goal:best option for less power consumptions @ more performance
