Do I need a Kona card instead of a video card upgrade? PC CS5.

I have limited budget at this time. Enough for one card or the other and I am getting conflicting answers so I want to bring it to the editors... Thank you again since this is a follow up?
The post house sent me footage ingested in AJA 10 bit uncompressed from a Teleciny in '93. 3;2 pulldown, interlaced, 525 line in MOV. format. In properties the Data rate is 27.2 mb a second. I spoke to the builder of my system and they recommended upgrading to a Nvidia 4000 from my current NVIDIA Quadro FX1700 since I am having issues with seeing the titles jumping and some jagged edges on shots with angles. DO I need a Kona Card instead since that would directly handle the AJA injest or will the 4000 take care of it? I am looking for a price point under a grand so probably the KONA LHe Plus.

Again I appreciate your time and experience in this!
