You have a very good card and should therefore expect excellent results from it ! However high performance cards can only give their best in good performance systems ? There are shall we say basic laws of diminishing returns that will affect overall performance of your computer setup ? The fact that you don't feel you are getting much more from your card when raising its clocked speeds from 475/950 to 565/1000 may therefore be a sign that its performance is being constrained by mobo/CPU/DIMM bandwidth bottlenecks ?? This is just a guesstimate on my part, since I don't know what the rest of your setup is like, or what criteria you were using to measure performance improvement ??
Also when measuring performance improvement from your card, it is best to stick to programs like 3dmark03, and aquamark3 and codecreatures1; good graphics card tests !! And use programs like 3dmark01 as a guage of overall performance changes ?? It is also most important to use same known and stable driver, like 53.03, for all testing otherwise it will be almost impossible to separate driver and card perceived performance issues ??
And you should try another 5950u bios, but don't worry about VIVO problems untill satisfied that another bios is going to give more than your original ??
I actually tried the Gigabyte 5950u bios, but found it average, and definately not in my top 10 ! However every card is different, so try the MSI that I use and the BFG and even the Leadtek, or anything else you fancy ? When and if you find a better bios, you may also find the new bios also provides the VIVO output you require ? Always remember a lot of 5950u cards provide very similar facilities !!!
my only other suggestion, is to modify your original bios with the "40" latency change as indicated in my 59xx bios modding Guide at first post of thread ! It will improve your cards memory bandwidth !!
