Bottleneck question

[happybelly]

I'm thinking of going SLI with two Geforce 6800 gt's. My question is, would a A64 3500+ bottleneck the video cards? I don't plan on overclocking at all.

Also, would a 550W Antec PSU be good enough for an SLI configuration?

Thanks in advance.

Unless you plan on playing in 1600x1200 with 8xAA,8xAF. Thats where SLI really shows its power. That SLI setup would be useless at 1024x768 without any AA as it would be cpu limited. PSU should be plenty.

I do plan on playing at 1600x1200 with 8xAA and 8xAF. The CPU won't hold the cards back at these settings?

Those settings will be very gpu dependent, and will require SLI to run at decent framerates. So no, the cpu won't be bottlenecking the video cards.

if that bottlenecked you, you'd be hard pressed to improve on it 🙂 fx-55 is only about 10-15% faster than your chip.

The monitor will either be the Dell 2100FP or NEC/MITSUBISHI FP2141SB-BK 22. So 20" viewable either way.

Is the fx-55 really only 10-15% faster than the 3500+?
