J-Mac, QwikMark is supposed
to work with everything from Windows 95 through Windows 7 64 bit. I found this author's comment

On my three year old dual core system I'm getting: CPU FLOPS- 16 Gigaflops; Disk Transfer- 98MB/second.
I didn't feel too bad until I saw the Core 7 i920 4-core's 72 Gigaflops benchmark.
