RE: INSTALLED G3
There are better cards, but I just got a GFORCE FX 5700 with 128MB of RAM from Tigerdirect.com for $139.00 which is not too bad.
The next step up takes you into three to four hundred dollar cards, which is a little rich for my blood, most of them are now PCIX which is not that common yet.
I have a Geforce 4 card at present and it works pretty well with G2, but it was time to bump up a bit and give the kids the old card.
You can get an refurbed Athlon 3000 system from tiger for $399.00 after rebate. It comes with a DVD burner, 512MB or RAM and has an AGP slot so you can put a full tilt video card in. It's a E-machines T-3092. I haven't seen anything close to it bang for the buck. (No I'm not affiliated with tiger, just a programmer and a happy customer). Warning: Make sure you are purchasing what you intend, as their return policies are not the best.
