Shorting Intel would be a bad idea. The voodoo2 is going to help intel
sell more high end pentium 2 processors. The folks at 3DFX have created
a 3D chipset so fast that now the CPU is the bottleneck in the system.
Tom's hardward site has a great review on these cards (diamond makes a 8
meg card, Creative labs has a 12meg). Some interesting things about the
cards are that there was almost no performace difference between the the
8 and 12 meg versions, at least for current games running at 640x480 and
800x600. On 200mhz Pentium systems the voodoo2 wasn't all that much
faster framerate wise than the original voodoo, but it could perform
faster at 800x600 faster than the original card could at 640x480. But
when you try a voodoo2 card on a 300mhz pentium 2 it just blows away all
the other cards on the market. There was a quote in the review from
3DFX saying that the ideal system for running the voodoo2 hasn't been
created yet. I guess if you buy it now you won't be upgrading your
video card for a while.

I am quake fanatic. I have a Diamond monster 3D video card with the
original voodoo chipset. I don't plan to buy a voodoo 2 chipset card
for a while because they are going to be very expensive until more
competitors jump into the market forcing Diamond's and Creative Labs
prices lower and because I'd probably have to upgrade my system to see
any serious performace increases over what I see now.
