I have vista 32 bit - dual 17 '' monitor - and obviously a older pc -lrb- p4 3 ghz -rrb- . my prior card be AGP 8x 128 mb geforce fx 5200 - so this be a upgrade . but the new card be pcus -lrb- standard , not pci-express -rrb- , so I be curious how the performance be compare to agp 8x . my other card start cause window to crash -lrb- video driver keep crash , and I try every driver with no luck -rrb- . the video on this new card be WAY better . my vista rating go from 2.2 to 3.7 -lrb- video still my lowest score -rrb- . the graphic rating be now 3.7 -lrb- from 2.2 -rrb- , and gaming graphic rating be now 4.5 -lrb- from 2.5 -rrb- . I can tell you color be clearer than before , more vivid than before , window drag smoother than before . also video be less jumpy , and hd video be actually pretty clear now . I can actually use Media Center now , before it would cause my whole system to bog down . maybe the pcus be better , since it keep the CPU free somehow . I be not a hardware expert , but the card be work perfectly . only issue be to make sure my monitor be at 75 refresh rate , otherwise text be move around -lrb- not the video card fault , just be sure to set the refresh rate properly base on you monitor capability -rrb- . a great upgrade for 50 buck !!
