Before you decide on a Radeon, read my misadventures before you buy.
I got a Radeon 64 at CompUsa a short time ago, I am using a NEC 21" e1100 monitor, Keep in mind I installed the Radeon on a clean system and I even tried it with no PCI cards to eliminate any IRQ issues while trying to deal with the WAVY screen the Radeon produced.
I tried and tried every option and every Frequency not 60,70,72,85,Optimal ot default fixed this WAVY screen that was giving me a splitting headache after about an hour of use each day.
My last resort was to call ATI, and I have to say that they have great customer support, they offered to send me some drivers not yet available.
Still to no avail, ATI offered to swap the Radeon64 with a Rage Fury Maxx(even swap) Well I gotta say that that wasnt such a deal as I paid 240 clams for the Radeon, and the Fury Maxx I simply didn't need as that was the card I was replacing in the first place......
Anyway I bought a Leadtek GeForce2 Pro and the WAVINESS is no more......
