NO!!
Not in my case.
I LOVE THE R200 but it doesnt seem to get along to well with the tyan mp 2460
The 3276 drivers ran like PURE crapola with the tyan and after a whole lot of tinkering to get the 3286 drivers to actually install it now only runs like HALF craploa. The 3dMark benchmarks with are off the chart and RTCW runs GREAT!!! As for other games not so the case. For example 1Inasne (a cool game if you ask me) doenst work properly, you get all the sounds and instrument cluster of the vehichles but no view of whats going on or where you are at.
Also after a good while of playing Return to Castle Wolfenstien I get little flickers randomly throughout the screen on my DVI panel almost as if it was like a bad signal on a tv.
