I have one system running a fcpga PIII 750 on an AOpen AX3SP mobo using an Intel 815EP chipset. I also have a socket a Duron 950 running on a Biostar M7VIG mobo using a VIA KM266 / VT8233A chipset. Right now the PIII system is my main system that I do most of my work and play on. The Duron system I use as a backup windows system that also dual boots linux. Anyhow, I was wondering if upgrading my Duron processor to an Athlon XP 1800 Thoroughbred processor, assuming all other things being equal, would make that system's performance alot better than the PIII 750 system. If the performance would be alot better than the PIII, I would consider it worthwhile to get the new processor and make the athlon system my primary system. Both systems are using PC133 SDRAM, not DDR on the M7VIG. Any opinions? Just wondering if it's worthwhile upgrading to the Athlon XP under these circumstances. Thanks!
