Thanks WMD.
If I took all of your suggestions guys and went "all out", I would have spent and extra $450-$550 - way over $3,000 instead of $2,600 (The $2,600 inlcuded an LCD for my wife's computer too), for what would probably amount to a 10% performance gain under optimal conditions.
An Athlon64 4800 instead of a 4400 would be an extra $180
Two 19" LCDs instead of two 17" LCDs would be an extra $100.00 or more
2GB CAS2 RAM instead of CAS3 RAM would be an extra $100.00 or more
A GeForce 7900 instead of 7800 would be an extra $60 or maybe more (prices vary wildly on these cards).
Anyhow, I said "I had a nice tax return" - not "I won the lottery". After paying off the credit cards, my budget for everything was $2,600. I ended up spending around $2,680. That's still way too much money to spend on a computer, but hey, if your going to burn your money, you may as well burn it on something you are going to enjoy.
I did a few benchmarks.
My 3dmark06 score was ~4600. This was with Windows X64 (I installed a version of it from work for kicks - I got it with regular XP since driver support for x64 isn't there yet)
With this areca SATA RAID card, the hard drives are insanely fast. My hard drives scored an index of 87 in sisoft sandra, and did seqential read and write operations at 118/115 MB/s respectively.
Memory badnwidth was something like 4.8GB/s - off the comparative scale in sisoft sandra.
I installed Far Cry and turned every setting up as far as it could go and I can't get it to go below 70FPS
FreeBSD installed with no problem on it. I did a quick package install of X/KDE and the nvidia driver and GLXgears runs at 16,000FPS. My old system with a GeForce4 did around 4000FPS in glx gears.
I compiled a new kernel in BSD :bsd: and it was almost done before I released the enter key.
