Thank you.. this is very helpful. It's a Precision 670 as follows:

But it's been refurbished and fitted with new CPUs, HD's and RAM

2x Intel 3.2GHz Xeon, SL7ZE
2x Seagate 15k, 73GB U320 SCSI
4x PC3200-1GB ECC RAM

Plus I added many more features post-delivery. Now please don't
start with how old and obsolete the system is because it works great
for me, and it can run FSX well enough with a nVIDIA 9800GT 512MB
card.

The system should be fine for your needs....although the ECC DDR may be a
bottleneck. Is this system running WinXP32? And did you simply remove the
FireGL drivers via Add/Remove and install the Forceware?
