Intel Core i5 vs. Core i7

Hey Everyone,
So I'm a developer who has a bit of a gaming habit (i.e. Starcraft 2) - and I'm completely fed up with my Macbook Pro. I purchased this guy about a year ago with a Core 2 Duo CPU (2.26 Ghz) and it's either Mac OS or the CPU - but I'm pretty much done with it. I can barely use the multiple IDEs I need day in and day out - and it heats up like nobody's business when I try to play Starcraft 2 on the lowest settings.
ALL OF THAT BEING SAID -
I'm making the switch back to Linux (and dual boot Windows for gaming). I know what I'm doing when it comes to getting just about any device working under Linux, so that isn't an issue. But what I really need to know is whether or not I'll be disappointed with Core i5 450M (2.40 Ghz), vs. a Core i7 720QM (1.60 Ghz), vs. a Core i7 620M (2.66 Ghz).
Right now if I had to pick between the 450M and 720QM I'd go with the 720QM hands down. For an extra $100 I get 4 real cores which makes sense considering all of the applications I have running for development work, etc. However, I was perusing Apple's site (mostly because I get pleasure out of buying their same system specs for much cheaper when not in apple's case) and noticed that their Core i7 CPUs are actually the 620M - not the 720QM. I spec'd out pricing on a 620M system and it would add about $400-$500 to the cost of the entire machine.
Given all of that - am I going to be disappointed with a 720QM system? Or will the built-in overclock take care of any issues there? Because these are all in laptops, I completely understand that 2.66 Ghz isn't likely to be realized if everything starts overheating, so is that another issue to take into account?
I guess my real question is this - is it worth the extra $500 to get the 620M?
P.S. - Why in the world is the 620M MORE expensive than the seemingly later-released 720QM ?

More about : intel core core
If you can use a 4 cores, the 720QM a great CPU, though its boosts up to 2.4Ghz as a dual core anyways so it would be alot better than the 530 in both cases.
The 620M is more expensive simply because its Apple. The CPU alone actually costs $30 less.
Which laptop are you looking at though? Since you don't want OSX anyways, no need to even consider Apple. Heres one with an 720QM+HD5650 for only $1000: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Ah ok - so you're telling me that the 720QM is still the better option ? If so that makes the decision a lot easier.

The 720QM is a great general option, choose the 640 when you only can use 2 cores period. Its advantage is simply a faster clock Slightly larger L3 and longer battery life if you care. Either CPU will be better than your old C2D however.
By Nvidia you mean this $900 one? http://www.newegg.com/Product/Product.aspx?Item=N82E168...
(BTW, what is your budget anyways? You could also consider the HP Envys..)

Yeah - Seems like the 720QM is where it's at for me then.
(BTW, what is your budget anyways? You could also consider the HP Envys..)
Budget is ideally sub $1000... but that's not firm. Essentially I'll sell my MBP for about $850 and have to only pay for whatever beyond that really...
The HP Envy's seem to have a bit of the Apple-tax effect... i.e. paying more for the looks, etc. Totally over it; I'd rather save the cash.
That's the one! Given the 100% 5/5 star ratings, I'm feeling good about it.
Thanks so much for your help!

Your a developer so the more cores you have the better, no?
Just pick the i7 720, you won't regret and stop hesitating on derivative's (i5/i3).
The 620 is more expensive due to it's initial release prior to the 720, higher demand and targeted as a primary model.

The 720 was released a few months before the 620.
