The MSI card is only 234 points away from the original GeForce 8600 GTS. When overclocked further, the NX8600GTS OC increases the gap to 643 points and notches a score of over 6,000 points.
The Radeon X1950 Pro seems to lose the SM2.0 tests due to low performance in the second test as we’ll see shortly. In the SM3.0/HDR tests the AMD card outperforms both the ordinary GeForce 8600 GTS and the pre-overclocked version from MSI.
We expected to see the AMD Radeon X1950 Pro lose the second test, but it is inferior to all versions of GeForce 8600 GTS in the first test of this group, too. MSI’s factory overclocking is not very effective due to the small frequency gain.
The MSI card needs additional overclocking to overtake the Radeon X1950 Pro in both SM3.0/HDR tests. The two cards differ by a negligible 0.2fps in the second test. So, everything seems normal here except for the first test from the SM2.0 group.
