Yeah..if you're producing and video editing and playing skyrim..I would pick the i7 one.

i7 if you're going to be producing/editing videos. Hands down. Even gaming, you should be fine with the 6730. I think it hits performance near the 5850m--about your average mid-range mobile graphics, plenty for playing most games on medium settings.

If the prices are the same, then most definitely, go with the i7.

6770m

6730m

The difference between the GPUs is the 6770m should be using GDDR5 while the 6730m has DDR3. This difference in VRAM bandwidth can account for 5-10fps in games.

If the dual-core was an i5, presumably [and preferably] 2nd gen SB, then I'd take the dual core/6770m. Skyrim shows little improvement with more than two cores and likes clock speed so any improvement in that over the quad is to your benefit. If it is an i3 dual core, then I'd take the quad because the i3 loses turbo, it is a zero sum game at that point for Skyrim.

Agreed.

Keep in mind that most video editing programs out there don't really utilize hyper threading but are slower with ht on. When using task manager to monitor them, you will see the hyper threading being used, but the usage on the cores drops, thus often being slower than just using the main cores in the first place.

Sony vegas pro and Adobe premiere will use all cores and hyper threading.
Programs like Nero, windows, Camtasia studio, though showing that they are using hyper threading do not take full advantage of the hyper thread, thus drastically hurting the performance of the main cores.
Games like BF3 also suffer from hyper threading.

Example:Nero 10,1 hour of video, i7 2600k,16gb memory.
Nero with ht on takes 16min to render a certain video file.
Nero with ht off took just over 8 minutes.

Skyrim does not have that high of system req.

You probably aren't going to be able to upgrade the gpu you will be able to upgrade the cpu. The 6730m will only have ddr3 the 6770m will have gddr5 which to me is a big difference, neither will be anywhere close to 5850m performance though.

Your using an apples to oranges comparison with using the 2600k as an example, but I can see your point. It was pointed out that if he was more concerned with editing, the I7 would be better, but if he is more concerned with gaming, the I5/6770m would be a better match. The 6770m performs anywhere from 15%-50% faster than the 6730m via the links provided in an earlier post for games.

It really boils down to which is more important to the OP, gaming, or editing.

i5 HD6770M, quad won't help in gaming, plus the HD6770M is faster with it's VRAM, but if it's the Dv6 HP, get a cooling pad, Hp's laptops get hot very fast while gaming !

I'm surprised I didn't ask this before--OP, what are the specific CPU's you're choosing between. The reason I ask is that it would be more preferable to choose a decently-clocked i5 as opposed to a low-clocked i7 with HT.

That is what I said, what brands are these cause if it is HP...I'd bypass it lol.
