Iused AMD years ago till i saw poser on a pentium machine of the same speed, it was rendering twice as fast so i've used pentium ever since....I had a P2 350 clocked at 450 that i ran with the fan upside done, as you can imagine it cooked, but its still running and still clocked LOL, anyway back to the story :o)...my sister bought an AMD machine, withing 5 weeks the CPU needed replacing, so a week after that i got a friend to build me an old clonker for music and the odd long render in exchange for an old laptop, it ended up having an AMD CPU, i wasn't to happy but gave it a go and guess what, its been fine for almost a year.....since then i bought a HP media center with an AMD 64 3200 in it and the thing flies along, now my other machine in a P4 2.8 so maybe the AMD is faster anyway (this clock speed lark is beyond me) or maybe its because the Pentium machine is badly in need of a format and sort out, but i'm changing my views on AMD....mind the AMD is noisier and has a fan that cuts in when its working hard, which is pretty annoying.....Goning to format the Pentium in a few weeks so maybe could do a better comparison....end of waffle ;o)..........Steve
