how about the i7 980, is alot more expensive but sill I think the i5 will be another waste of money
or if you can sugest me another i7 would be great
Super Mario Galaxy 1 and 2 need beastly machines to reach and maintain fullspeed (or speeds close to it) with LLE audio. Most people would recommend overclocked Sandy Bridges, especially if you're using LLE (necessary for some parts). F-Zero GX is pretty demanding as well. Most games that need LLE in general are pretty demanding as well. Xenoblade is pretty tough on the hardware too.
For Metroid Prime, my drops aren't nearly as drastic as yours (60-25). Mine's like 60-45, even with LLE audio (HLE messes up sometimes, it's kinda annoying). It only ever dropped to 30 during the frigate cutscenes, which is expected on most systems, I guess. Remember though, my CPU is still at stock; it'd probably run Metroid Prime without fault on higher clocks.
But as for the i7 980, seems like a waste of money to me. An overclocked 2500K will do great on many of the demanding games already; there isn't much it has problems with when it comes to Dolphin. The 2500K is a better deal for its price.
