I have an older system which carries a P4 2.8 400MHz cpu. The memory is rambus ( Sucks, I know ) PC800 and it also came with a PNY Geforce 4 Ti4600 AGP Graphics Card.
Question: Will upgrading the video card to a 6600GT / 6800GT be an over kill and make the cpu and memory a bottle neck, or give some added performance. Also The power supply is able to support the newer cards, and changing the motherboard etc. is not an option.
I put a 6800GS AGP into my system with a Prescott 3.0E and unlocked the pipes which made it nearly (if not exactly) like the 6800GT. There was a huge difference in performance over my old FX5200. Of course that's an FX5200 so of course there would be a huge difference . I'm not sure if anything is bottlenecking it but I would like to know how to find out if that's possible.
