i want to get a new video card for my computer so that i can run some newer games because my video card is only a geforce mx420. I was looking at the ATI Radeon X800 XT 256MB AGP card and its system requirements are Intel® Pentium® 4/III/II/Celeron™, AMD® K6/Athlon® or compatible with AGP 8X (0.8V) / 4X (1.5V).

My system has
k7t266 pro 2 ver 2.0 motherboard
amd anthlon(tm) XP 1700+ 1.47 GHz
768 MB ram
The AGP Spec on the mb supports AGP 2.0 compliance in AGP 1.5volt

i know that if i get that card and its backwards compatible it will only run at 2x speed, so is it worth it to get that video card. I would like to just get a new computer, however i dont have the money to consideirng i just used it to buy a new laptop for college. How do i know if this card is backwards compatible tho??
