I used F.E.A.R.'s built-in performance test. This
generated results in minimum, average, and maximum frame rates. F.E.A.R.
also provides the percentage of frames that are less than 25 (<25), between 25
and 40 (25-40), and greater than 40 (>40).
The first set of tests below were with
my previous system which consisted of an AMD Athlon 64 3500+ and 1GB of
Mushkin (512MBx2) PC-3500 system memory.
On the following page, I've posted the results of
the same benchmarks with the MSI 7800GTX 512MB card on
my current system which consists of
an AMD Athlon 64 X2 4400+ and 2GB of Corsair XMS Twinx PC3500LLPRO system
memory.

with single 7800GTX 512MB

The point of including the results of the 7800GTX 256MB in SLI mode was not
to compete with the MSI 7800GTX 512MB card. Clearly, the SLI configuration would
(and does) win in every test. What is noteworthy, though, is that in the 4XAA
tests you can see that the MSI 7800GTX 512MB card impresses over the single
7800GTX 256MB card. It actually does puts up some respectable numbers even when
compared to the SLI results until 8XAA is involved.
