almond Posted November 4, 2009 Share Posted November 4, 2009 For better H.264 playback and converting, I bought a leadtek nvidia GTS 250/ 1GB to replace 7300GT/ 256MB on my 975 xbx2 mobo. But the GTS250's performance and xbench ( quartz, openGL ) are little behind 7300gt I've tried EFI string, PC EFI v.10.5... the same. GTS 250 works fine, but slower than 7300gt... why?? I know the gts 250 is an upgraded 9800gtx Any idea? mobo: intel 975 xbx2 ram: 4GB OS: 10.6.1 by chameleon 2 RC3 Link to comment https://www.insanelymac.com/forum/topic/195742-new-gpu-slow-speed-sorry-for-duplication/ Share on other sites More sharing options...
