ATI Radeon HD 2400 Pro 256MB-to-VisionTek Radeon HD 4570, 1GB PCI e 2.0

Running in a Dell XPS 420 with XP SP3 (came with Vista but I stripped that
off and put XP back on it).
Dell says the VisionTek Radeon HD 4570, 1GB PCI e 2.0 WILL work with my
machine. I typed in my serial number AND chatted with a Dell "specialist".
Am I going to see a substantial (noticable) difference in the way my
slideshow/videoshow program runs? Will it execute commands faster and will
the videos be smoother. For the most part, they are smooth but depending on
the slides styles I use, they can be a bit jerky. Power supply min is 400
and my ps is 375. I guess with my serial number, they should KNOW what I
can and can't run, right??
Thanks
Monica
