Actually, really depends on display
Just last night my neighbor and I went to CompUsa, where he bought a Viewsonic 15" VA550, with free ($99) matching Viewsonic keyboard and mouse for $549. Went to his house. I installed 6.31 drivers on his four year old computer/Win98/TNT32 video card, and suprisingly, the thing fired right up and looked REAL good!
Think I'm gonna get a wall mount version of same.
Edit: Thats a PCI TNT, not even AGP
