I have an ATI Radeon 9500 PRO 128 MB Graphics Card installed in my system of P4 2.4 GHZ, 512 MB RAM, 845G chipset. I am finding it a bit slow to meet my video editing requirements and am thinking of upgrading. Is it advisable to go for a new mobo and processor with same AGP 8x Graphics card (choice limited to mobo with AGP slot with 865 or 875 chipset) or directly go for 915/925 PCI express cards. I am on low budget and hence trying for a value for money solution. Will you please help.
