well if it's a k6(2 or 3 or whatever the mobile one was called - 2+? i have no memory whatsoever) it's what, socket 7? or super socket 7?
I'm hoping you're wrong, or they're wrong, or whatever. a k6 is a horridly slow, 8 (?) year old processor model. They maxed at what, 500mhz? the same as the entry level slot A athlon, iirc. but as i said, it was many years ago.
Basically, ss7 motherboards and chipsets are supersucky by today's standards. and yesterday's. and last week's... and so on.
I'm thinking, hoping, and praying that you're mistaken, and that it's a a64 you've got. I can't think of any other cpus with a 6 in the name, tbh. if it's an a64 then you'll be fine, and i want one. I'm skint at the mo, but i'll have money soonish, so i'll be going the 64-bit route.
but yeah, if you paid actual real money for something like that (i found a whole pc in the street that's faster than a k6, and only the monitor was broken - thankyou, idiots!) then you were ripped off.
actually, a k6 should really struggle with winxp...
