sebetulnya ada yg namanya pgc (parallel graphics configuration) dari
metabyte/wicked3d .. masih inget? :)
udah diumumkan sejak taon lalu & udah sempet ditest dengan dual
voo3 maupun dual tnt2 (cmiiw) dengan hasil memuaskan. malah konfigurasinya
bisa 1 card di agp, 1 card di pci, kerja bareng .. nggak tau kenapa sampe
sekarang blom ada kabarnya lagi.

kayaknya dia cuma pake trik driver + output combining circuitry aja tuh,
mustinya sih murah ..
.. paling nggak bagi mereka2 yg sampe merasa perlu punya 2 vidcard di satu
kompie .. ;)
ps: bagi para voodoo owners yg blom tau, wicked3d juga bikin driver mini-gl
khusus voodoo buat game2 opengl. performa + kualitas image-nya imho jauh
diatas driver standarnya 3dfx (di gue: 47 vs 59fps on q3 =) silakan dicoba

Wicked3D PGC has several different components. Obviously, one component that
is required is a pair of Wicked3D PGC compatible video accelerators. Because
Wicked3D PGC technology was designed without specific platform requirements,
it can be ported to different video chipsets. Of course, these Wicked3D
accelerators can function independently as well as in PGC mode. This
provides a user the ability to upgrade the performance of a Wicked3D system
without having to discard their current Wicked3D card when new software is
introduced that require more rendering performance. In PGC mode, the two
video cards will be connected internally via a cable. In addition to the
pair of PGC compatible accelerators, the PGC system includes an external
hardware component that takes the outputs of both video cards (the upper and
lower regions) and integrates them into a single image for the monitor. This
component will also allow the use of the two Wicked3D PGC accelerators
independently, in a Windows98 multiple monitor configuration when desired.
The final and most critical component is, of course, the software drivers
that allow all the hardware components to work together. Metabyte has
leveraged its many years of experience in the device driver industry to
overcome inherent design and graphics issues to create drivers that allow
the Wicked3D PGC system to perform efficiently.
