Project Snowblind

We’ve seen this already. The two complete PCI Express x16 slots don’t have a slightest effect on the performance in games that don’t operate with complex textures, particularly in games that have come to the PC from game consoles as Project: Snowblind did. The results of the A8N-SLI Premium and A8N32-SLI Deluxe coincide to a tenth of an fps.

Quake 4

This recently released title doesn’t reveal any big differences between the two mainboards, but it is in fact characteristic of the new games from id Software to have rather simple textures. The low texture quality is made up for with the wide use of bump mapping and with a complex lighting & shadowing model. The amount of data transferred between the SLI-connected graphics cards is relatively small and keeps within the bandwidth of two PCI Express x8 slots.

The combined power of two GeForce 7800 GTX allows playing Quake 4 even with 16x SLI AA turned on, but you may want to limit yourself to 8x SLI AA to play in 1600x1200 and have a smaller risk of encountering a slowdown.
