I have 2 related questions:
1) Is WCG accumulated points a subset of BOINC stats? Are points, comparable computation load wise across projects? Say WCG vs Milkyway@home if I were to run both only on main CPU one at a time? Will make more sense when you read question 2.
2) Are BOINC credits form Milkyway@home compatible to WCG stats? My MW@Home is mostly running on my video card and I have about 57,000 BOINC credits and about 5000 WCG credits, does that roughly mean that the processing power of my Radeon HD4870X2 is 10 times greater than that of my main CPU? I do realize that Radeon only does integer while main CPU does FP calculations, but still with properly written code for each one, should I assume that my video card is contributing/crunching 10 more than main CPU?

I guess another way to compare GPU to CPU processing is to say this:
Earning 10000 points running GPU will bring MW@home problem 10 times closer to being solved than earning 1000 points running only main CPU. Here 10 times closer does not mean reducing overall work load left 10 fold, but rather increasing work done by tenfold.

Thanks
