Well people I just upgraded to gtx-260 from my 3870. CPU and rest is same, even dolphin version. Difference is BIG - B-I-G.!! Now in mario I get 90% time full speed, on begining no matter if I start move or not I get full speed 60fps, walking into first city it get just a little slower, but only some short moments. But thats not important, what IS important - mario when running he really run, it feels almost too quick! Before even when I got sometimes reading like 50fps in some cases, its not same speed! Now even 40fps fees good. Also tried metroid prime beginning, got at least 24-35fps where I got arround +-10 before in very beginning, but it just feel ok no matter what. Overal, changing gpu/vendor gave me incredible difference and I tested on 640x480 only yet still... Intel+nvidia+creative F.T.W.
