Did you try Futuremark?(3DMark2001 etc.)
They've dad a databse of CPU,GPU comparisons for years. You need to
register(free) to get access to the result browser


Is there an online resource/techie site anywhere which compares the
mainstream, past and present, nVidia Geforce boards? I'm looking to compare
RAM/GPU speeds, technology onboard (T&L? AA?).
