Re: Bought new recomended graphic card from sony's site, now vegas is slower then ever why?

Yes that is correct, when I upgraded my card I went & bought the NVIDIA GTX 570 once it was installed with the current new drivers, that's when the system took a turn for the worst, instead of upgrading performance, it actually decreased performance drastically! this is why I've been flooding the forum here with questions? trying to figure out why? so after not being able to get my system to play back smoothly on one solo track I exchanged the GTX 570 for the Radeon HD 6950, thinking WELL let's try this one, HOWEVER after putting in this new card, there was still the NEW ISSUE of all this skipping frames.

Stephen after both cards being FAR worse than my old card, I went out & bought a FAST solid state drive for my operating system, installed windows 7 64 bit onto it, & installed the latest version of Vegas, EVERYTHING now is up to date & brand new,
BUT NOTHING made a difference within Vegas, even though my over all rating of my computer jumped from a score of 5.6 to 7.1 Vegas is running poorer now that I have upgraded my graphic card, what is causing this DECREASE in performance? within Vegas? is it GPU features? I dont know? all I know is something is not right!
Selecting no GPU within Vegas, under the preference video tab, does not improve or make Vegas ANY DIFFERENT no change!

Again my old card had no GPU these 2 new cards do,
do you think there might be an issue with GPU & uncompressed AVCHD files, at this point it's ALL I can think of? only 1 thing changed on my system when I first started this task, & that was simply up grade my graphics card, & I've done it now with 2 different cards both having the same results
DECREASE IN PERFORMANCE
in conclusion my old Radeon HD 4670 card that had no GPU functions on it ran WAY,WAY, better, the million dollar question is WHY? this card is at least 3 years old, small & tiny, so I must be doing something wrong! but what?
