I don't think you would get much of an improvement in performance going from a 9800pro to a x700pro, unless the x700 overclocks like crazy. It might be better to upgrade to something like an X800XL.
Well... There was a "home" edition of Windows 2000 in development code-named Windows Neptune, but it was canned before its release. I'll bet Neptune did not have SMP support, but we'll never know unless some beta tester has an ISO laying around. It had some pretty neat features for the time too.
What? Do you mean their clock speeds aren't scalable? My 3000+ Athlon 64 S939 overclocks just fine to 2.6 GHz from the default 1.8 GHz. A 800MHz overclock seems pretty scalable to me. Or did you mean that they aren't usable for multiprocessor systems?
It's hard to go wrong with either card. The only reason I returned my 6800GT and got an X800 instead was that the 6800GT had some weird IRQ conflict with my TV tuner card. Of course I'm very glad that I was able to get an X800 Pro VIVO and was able to mod it to an XT PE, but the 6800GT was...
I expereinced no negative effects after flashing, only very positive ones. Maybe it got a little hotter, but I'm not sure since I have a Zalman sandwich on it.
I got a 36GB Seagate Cheetah 15k RPM SCSI Ultra160 68pin LVD HDD, a WD 250GB ATA HDD (for RAID-1 storage), and a Palm Tungsten E. The SCSI drive = way fast.
I've installed that heatsink on about 20 computers so far and I haven't had any problems. Temps are fine, it's properly secured, and it's easier. This of course won't convince anyone who wants to be absolutely sure, but where's the fun in that?
You don't need to take off the backplate if it's the retail AMD backplate. Just take off the old heatsink, unscrew the plastic mounting tabs, and screw in the zalman "nipples" used to install the zalman heatsink. Then just apply the AS5 and screw the heatsink into place.
That card has a removable graphics chip. They swap an old buggy chip for a new fresh updated chip and put it in the same card. The clamp holds the chip in place on the card without having to solder it on.
I use RM Clock to reduce the multiplyer and voltage on my Athlon 64. It reduces the idle temps, but more importantly, it reduces your computer's power consumption. Unless you're using your computer as a room heater (or running folding@home) less heat is always better.
I'm running all that you see in my sig and my 430 truepower still runs fine. The 12 volts rail dips down to 11.91 or so when I'm overclocking like crazy, but for the most part I have no problems with it.
