So i made a post a little bit ago about a gt 240 vs 9600 gso. I got my answer and planned on getting the gt 240. But then i looked up my motheboard (ecs pt890T-A) and it has a PCI-E 1.0 slot. Would i have any problems installing the new card in my mboard? And more importantly would the upgrade of video card (9400gt currently) be worth it considering i have the older PCI interface? Basically, would my older interface be a bottleneck in performance, negating the video card upgrade?
