My husband and I are new system builders. Our first experience was with Windows Home Server, which was in a very basic hardware configuration. Anyway, our specs are an ASUS motherboard PK5-E/WiFi-AP, Intel Core 2 Duo 2.4 Ghtz, 2 gigbyte (adding more soon) 300 gigabyte SATA hard disk, ATI HD 2600 Pro video card, Creative SB X-Fi HD sound card, Marvell Yukon 88E8056 PCI-E Gigabyte Ethernet Controller, Realtek RTL8187 802.11b/g USB 2.0 Wireless Network Adapter, flopy disk drive, Pioneer DVD-RW DVR-111C ATA disk drive, Agere OHCI Compliant IEEE 1394FireWire and other goodies just for starters, with a Antec 500 Watt PS, and an Antec case which rocks. In our humble and inexperienced opinions anyway. lol We installed Vista Ultimate about a month ago, and then installed SP1 two weeks later. I must say that the system does seem snappier with SPI than without. I fully understand most of the fixes in SP1 are under the hood, and have read up on what they are and what they fix. Our installation went smooth and completed in under fifteen minutes. I think this is mostly due to the fact our Vista installation was so new. Not a lot had been added to the system, so there wasn't a lot to work around. Everything runs fine, not a single hitch. I have spent a great deal of time getting to know Vista Ultimate. I think Vista is a huge improvement over XP Pro. This system almost takes care of itself. I like the Problem Reports and Solutions, the revamped Event Viewer and Proformance utilities, and even the UAC is worthy of getting use to working with. My only complaint is I believe Vista should enable SATA without having to go through the hassle of "adding additional drivers". Due to our newness, we did not know we needed to add those drivers and so our SATA hard disk is actually running as IDE, and can only be changed by a full reinstallation. Thanks for starting this thread, this is my very first post in this group. This topic is a good way for me to get my feet wet here. I found the group through pure chance, and hope to receive some help on the SATA driver installation. SerenityRee
