But .... The Asus boards are supposed to be OK. You should be able to get one at a reasonable price with the VX or HX chipset. I don't believe there will be any performance difference between an Intel and and an Asus motherboard; they'll both use the same components and general board design. It's the chips used that count these days. We just went through a similar exercise, but my information is now 3 months old, so it's possible everything's changed. The VX chipset supports RAM configurations up to 128mb, and supports FPM, EDO, and SDRAM. The HX chipset supports RAM configurations up to 512mb, and supports FPM, EDO, and ECC. I don't know about speeds; I suspect they're the same. Check out the specs on the chipsets - they're available on the Intel web site. Cyrix chips are OK if they match the motherboard. Certain rev Cyrix chipsets don't work with certain rev motherboards. Also, the Cyrix chips are optimized to run 16 bit code (e.g., Win95). However, we closed our eyes and threw a dart at HSB Laboratories (800 497 0401), and bought a SL586V motherboard and a Cyrix P150+ processor (motherboard for $141 and processor for $160, 3 yr waranty, company blessed by the local Better Business Bureau). The motherboard design is new this year, and I counted on them to supply a Cyrix processor that was properly matched to the motherboard. We were extremely pleased with the result. Between the processor speed and the disk IO (EIDE PIO modes 0-5), my impression is that the machine was faster for compile/link jobs than a Sparc 5. I have no benchmark data however - the machine has already been shipped to a customer. We had no trouble running RedHat 4.0 on it. One item that apparently makes a significant performance difference is the size of the L2 cache. Most machines are equipped with 256k; 512k is worth the $20 if you are interested in performance. The more significant feature for a machine is disk transfer speed. Be sure you get a fast disk, and support on the motherboard for the faster IDE transfer rates. Finally, if you really want the fastest 32 bit performance, get a Pentium Pro, with an Ultra SCSI Wide disk. Good Luck!
