Gaming Laptop: 2.6GHz Dual vs 1.8GHz Quad

I am looking into purchasing a gaming laptop as I will be away from my desktop for a year or so. I was curious should I go for a higher clock rate or more cores for gaming? ie. a dual core 2.66 GHz i7 620M vs a quad core 1.86GHz i7 840M.

Few games are optimized to take advantage of 4 cores and so I was wondering if it would be better to take the higher clock rate.

I just had a thought though. On the i7 840M, does turbo boost kick in when only 1 core is used or can it work for up to 3 of the cores? If it can work for at least 2 cores then my question is answered. haha.

well, with turbo boost, the difference is nullified. also, get eh i7 720m, not the 840. the 720m is gonna be the better buy over both of them.

does Intel's Turbo boost support boosting 2 cores? Last time I checked Intel's turbo boost only boosted a single core on single threaded apps. So If I am playing a game optimized for dual cores, I will have 2 cores at 2.66GHz vs 2 cores at 1.66GHz (using the 720QM).

not so, the i7 actually runs at 2.46 GHz when dual core applications are detected. however, there is also a large difference in architecture, and just because the i7 has 4 cores/ 8 threads and something only uses 2 of them, it doesnt make the rest useless. theres a lot more running in the background when you are gaming than you think.

Haha. I didn't think about the background operations. I was still concerned with the 1GHz loss, but 2.46GHz does nullify that. A 720QM it is. Well we'll see. I'm still browsing brands and models.

I'm actually looking at xotic right now. I'm not sure yet, I may go as high as $2300. It depends on what the right parts start to cost me. I will be content with a 15 to 16 inch screen. There is a large price jump to get those 17's and 18's.

cyber power you can get a 17incher, 1680x1050 (good res for laptop gaming) a 5870, i7 720qm, 4 gigs of ram, and a 7200 rpm 500 gig hdd for just under 1500$. of course you could get a ssd and more ram if you wanted.

That's not a bad deal. I think SSD's are great for productivity, but too expensive for gaming, unless you don't mind constantly uninstalling and reinstalling games and 4GB's of ram should be plenty.

What do you know about Sager's? I found one on Xotic, Sager NP8690. It was just over $1600, with a 15.6 inch LED screen, 740QM, 5870m, 4gb, 500gb hdd.

That is pretty much a 17 inch version of the Sager NP8690. haha sweet. That may be the one.

EDIT: It's the 8760 and not the 8670 right?

I think I'm going to go with the 8690 that I first saw. After I take the OS off (I can get a student discount and get win 7 pro for $30) it is $1450 and all I lose from the 8760 is a couple inches on the screen. Thanks for all your help. I'm going to browse a bit more before I buy it though.
