Tried out these drivers. Seem pretty decent on an SLI setup but haven't played a ton. Not seeing big improvements tho, still stuttering and so forth. With respect to the whole Beta issue. People have the right to be angry with these drivers. EVERY TIME I speak with Nvidia support regarding a current WHQL driver bug they fall back on the statement "Give the beta drivers a try when they launch". This is usually the final answer get to any problem and it means I have to keep waiting for a new driver. This type of customer service response builds and expectation for customers that the next thing to launch will solve some of their issues and at least be an improvement in some way from previous support. I do not agree that anyone frustrated with these drivers should be reprimanded. I do not expect any guarantees with Beta drivers; however, Nvidia has failed time and again to produce clear improvements from driver to driver in this 258 and above series.
