Pros: No problems with the drivers in the short time I've been using it. Right now I'm running it clocked in at 940Mhz core and 1160Mhz VRAM. At these settings it clears Vantage on High with no artifacting and my score went up from H6153 on my 512MB HD4870 (tested on a clean boot) to H7623 on this 4890 (without trying a clean boot yet.) That's something like 24%. How can you NOT love that?
Cons: ATI Overdrive clocks mine in at 990Mhz GPU and 1190Mhz VRAM, but it artifacts like mad at those settings in 3DMark Vantage. But let's be honest, that's a ridiculous increase from the stock speeds of 850/950.
Overall Review: Only had it for a few days but what I've seen so far is truly amazing me.
