Brisby power, how much?

[CptFalcon]

Hey there guys I got a somewhat interesting question for you guys. What kind of Brisbane processor power (GHz) would I need to fully power an 8800GT or a ATI 4850? Right now I have a 65w Brisby 4400+ that I have OC'd to 2.7GHz from 2.3GHz and my frames in Warhead have increased slightly.

If anyone could provide assistance on this I would very much appreciate it.

It depends on the game and settings.

My Brisbane at 2.9 GHz gave me 56 FPS running the UT3 ShangriLa flyby at highest settings at 1680x1050. My current Phenom at 2.5 GHz gives me 98 FPS in the same benchmark. Howeever, with 4X AA/16X AF, both CPUs produced exactly 55 FPS.

That's just a flyby with no AI, physics etc. active, though. During actual gameplay there'd obviously be a difference between the CPUs even at 4x AA.

Also other games are more CPU dependant. I don't think there's a Brisbane out there that can consistently max out a 4850 in some of the latest games at reasonable resolution and AA settings.
