I have a NVIDIA GeForce 256 video card.... is that up to date enough? - I would hope so, but I am a driver not a mechanic.
Let me know if you decide to upgrade. I'll direct you to a site where you can get DELLS for 1/3 of the price. No reason to make you wait actually, just go to DELL and check out refurbished systems. The best prices are available around 5:30AM Wednesday and Thursday morning. Otherwise all the good deals get snatched up.
