If a desktop PC will work for you, there are some very inexpensive 4
core AMD Phenom II machines with 6GB for sale these days in the $500
range, including a pretty good Firewire port and Windows 7 64 bit. I use
one from CompUSA with my Flex-3000, and also run a Flex-1500, RMS
Pactor, RMS Winmor, DDUtil, MARS-ALE and several other things on it at
the same time, 7x24, without problems.

This PC would be fine for a FLEX-1500 since it would not have to deal with the
isochronous Firewire overhead and higher sampling rates.

Subject: [FlexEdge] Is this PC good enough?
I've been playing with 2.0.16 in demo mode, and really like it. So much so that I am now
looking (again!) at buying a 3000. The question now is, is my PC good enough? I've read
the KB article "What kind of computer should I buy ...", and have come to the
conclusion that my PC is below the minimum requirements.
However, before I discard it completely for Flex use, here are some of its
capabilities:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Dell 8300
Pentium 4A, 2533 MHz (4.75 x 533)
L2=512KB
Motherboard chipset: Intel Canterwood i875P 1GB Dual DDR SDRAM 333MHz
Video: ATI Radeon 9800 Pro 128MB
Win XP Pro 32-bit
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
DPC Latency:
With no apps running: about 5uS
With 2.0.16 running: mostly 15-50uS, peaking very occasionally to 150uS max
2.0.16 CPU utilization (demo mode, no Flex hardware, 192kHz audio):
Mostly around 45-50%
With NB enabled: up to 90%
Bottom line: With no other apps running, is there any chance that this will
fly, if only as a stop-gap until I get a more suitable machine? Or am I simply
wasting my time?
