I'm looking to buy a new computer towards the end of this year and am doing some preliminary research trying to figure out what i'll need. I've been looking mainly at Dell's because 1. that's what i've had for the last 3 years and have been happy with. 2. I wouldn't know the first thing about building a computer and even though i'd love to, that's the kind of thing that would frustrate me immensely when it didn't work properly. 3. They seem to have a good price/performance ratio. My questions at this point are, I am going to get a "near" top of the line video card with my new system (currently probably a Radeon 9800 Pro). I noticed the Dimension 8300 has a 250w power supply compared to 400w (i think) for the XPS system. Will this make a difference to me using this video card. Secondly, can someone give me a very basic idea of what i need to know about prescott? If i get a computer before prescott comes out is that going to kill any chance of upgradeability? Finally, what is the deal with this Gigabyte ethernet connection. I realize it probably isn't available (as a home internet connection opetion) right now, but will it be something i need in the next few years? Currently i'm thinking about getting a Dimension 8300 with 3GHz P4, 512Mb RAM (upgraded to 1Gb later when i have money), Radeon 9800 Pro, DVD+R/RW drive, 80 Gb hard drive.
