VIA chipsets are best for 9x. NForce2 performs really well, but I've found it to be unstable at times. VIA is slower, but it's rock solid. AMD procs are far better in price. A Socket 754 Sempron 3100+ 64-bit is 50 bucks at Newegg. 98SE runs nicely, and newer OSs (Linux, anyone?) will fly on it. Nvidia chips beyond the 6 series are overkill. AGP doesn't allow much of a performance boost, and better cards require higher driver versions that are optimized for NT kernels. I haven't used ATI in years, but I'm told the 9800 is a very good card for 98SE. Wattage is pointless in a PSU. What you're looking for is something that costs at least 30 bucks, from a decent brand. Cheap 500W power supplies almost always blow out by the time you hit 400 watts, dono't waste money on them. With a system like I outlined, you'll never need more than a 350W unit unless you're running a server with a few hard drives. For memory, I've also found brands not to matter much for performance. Quality control varies between brands though, so go with a pretty big name. I'd suggest Kingston, they're affordable and seem to have a low failure rate. Avoid PNY, I know way too many people who had to return those chips. Monitor is all about what you can afford. LCDs need less power and take up less space, but a CRT will have a better picture that some of the cheap LCDs. If the video card has a port the monitor can plug into, then 98SE will be fine with the monitor. This is all just based on my experiences. I'm sure others have had different expierences, so take it with a grain of salt. Hope it helps.
