Hello, I have a P4 3.0 HT processor and 865 Intel mobo with AGP slot and SATA I support only. Currently its assembled with 2GB DDR RAM, 2 SATA drives 160 GB and 250 GB each (Seagate) and a ATI Radeeon 9600 pro 256MB gfx. . Is there any alternative for my mobo as its performance really sucks?? Thanx in advance.
