At first this thread seemed pointless to me, for it is not structured... BUT the question IS interesting and since many people have gone through the trouble of summing up their current systems, so will I too.
A. Duron 650@950 (yeah, I squeezed out another extra 100Mhz thanx to Tom's tip in yesterday's Duron 850 review (close the L7 bridges for 1.85V)), 128MB PC133, 13.6GB 66Mb/s, Chaintech 7AJA mobo, Innovision TNT2 Ultra, Sony CRX140 8x4x32, AC97 sound.
B. Celeron 300@374 (=4.5x110Mhz ought to be 500Mhz, not?), 64MB PC100, 6.4GB + 2.5GB + 2.1GB, Promise U-ATA66 card, DFI P2XBL mobo, Diamond Viper V550 AGP, Actima 32X, OEM Yamaha 16-bit sound.
C. Intel P120@133 (yeah, even this one is overclocked 😉 ), 32MB FP, 540MB, Aska SST5805 mobo, OEM S3 Virge DX/GX, no CD-rom, SB16VE sound.
I'm still pretty happy with this collection, especially the real fast Duron and the rock stable Celeron.
Keep it cool!
