The OpenMP option in dolphin is only for texture decoding. I for one have never seen it make any difference in performance at all. It's just meant to reduce stuttering in a few games.
The same goes for openCL.
Quote:I do have windows. Ancient versions only support OpenGL, Older versions of dolphin run much faster on windows with D3D9, but newer versions appear no much difference, at least for games mentioned above. The nvidia driver for linux has made much progress.
How ancient are we talking? D3d9 is supported by windows 2000. So unless you're using windows 98 or earlier you should be able to use d3d9 as long as your hardware supports it.
Quote:Dolphin already support quad cores,to be more precise,it uses 3 cores.
3 is not equal to 4. So no, dolphin is not a "quad core app" or however you want to say it.
Honestly, the i5 is all you really need. For physics on most high end PC games like battlefield 3 you don't need to go any higher than an i5, and an i3 usually works just fine. As for wii and gamecube games, even though they are more cpu intensive than gpu intensive, you still won't need any higher than an i5.
I planned to use the laptop for 4 or more years. And I have a budget of 1000$ or so, so I want to care for the need 4 years later.

It has been working at 80ºC for 5 years without any problem. In fact I have contacted with my hardware provider and they said it's Ok as long as under 120ºC.

I mean ancient versions of dolphin. I started playing the Wind Waker at 2006. At that time there was no D3D11 and D3D9 didn't work. The following years have seen a great step made by D3D9. It's much faster. But now, the speed of OpenGL has caught up too. Maybe It's linux OpenGL vs Windows D3D9. The OpenGL under Windows is still slower.
If you're gonna use it for 4 years, you might as well just wait for ivybridge, better to have the latest thing when it comes out immediately knowing it will be the trend for awhile

80C under full load is not the same as saying it has been running at 80C for 4 years, it has not been under heavy load that entire time.
And for the record 80C is right on the edge of what is considered safe and unsafe for sandy bridge.

Then whoever you spoke to is a complete idiot, that's physically impossible. Silicon MELTS at 120C. Most modern cpus are designed to remain under 70C but some of the better architectures can remain safe at 80C or in some rare cases even 85-90C. No cpu ever made in the last 40 years has been able to remain stable above 100C, that is a fact. Older cpus were a lot less tolerant of high temperatures, even the best models would begin to show microcode bugs at temperatures above 50C.
You have a sandy bridge architecture which is safe long term up to about 80C, it will function in the 81-90C range just fine but it is not safe for long term use. At 100C the system will shut down to prevent permanent damage. Don't believe me? Try it. Or better yet look up the Tj max for your cpu model, it's 100C just like all sandy bridge chips.
I currently run an i5 2500K desktop @ 3.1GHz, and an i7 2670QM @ 2.2GHz on my laptop. I must say the i5 wins hands down. I know the clock speeds are way more and it is a desktop vs laptop, but the difference is major, but on pure benchmarks my i7 wins, not in dolphin though. Not to mention heat and battery is better like mentioned above. OC cabapility too.

Yet another advantage of graphine as the wafer. Shame it will take at least five years for fully functional prototypes.
I bet you're sorry you asked now
