Intel D915GAG FSB: 800MHz Processor: Intel Pentium 4HT (3.0GHz) PSU: 250W Support for PCI Local Bus Specification Revision 2.2 Support for PCI Express Revision 1.0a 1. Can I install a PCI-E 2.0 video card? I'm interested in the ASUS EN210 2. Can I upgrade to a 600W PSU? 3. Does a slow Front Side Bus affect the performance of a GPU? If so... 4. Is 800MHz enough to use the ASUS EN210 to watch full HD videos? All I want is to be able to watch Full HD movies and YouTube videos. Thanks in advanced!
