I install this video card in my 2001 Sony VAIO PCV-RX850 APG Slot . I power up the computer and Voi La. . I open Google Earth and the difference be phenomenal . work with Daz Studio 4 and Poser 8 , my system -lrb- xp , sp3 -rrb- do not crash nearly as often as it use to ` out of memory , program must close ' . these program work much faster with the new video card , presumably because of the additional RAM on the card itself . for example , render time in poser 8 take half as long as it use to with the onboard Sis 650_651_740 Chip type : Sis 651 rev 00 . I be very happy with this card .
