Intel i7 620m vs i7 720qm

Hello and welcome to the forums  
i7 720QM would be better in multi threaded apps/games,whereas i7 620M is better for non-multi thread apps/games.
And GT 330M is a mid-range laptop card which can handle new games on medium-low settings

Hi newcomer and welcome to the Tom's hardware forum.

All the components that u list are portables, so, I will assume that u are looking for a laptop right?

The i7-720qm is much better and performs very well against the i7-620m. Like Maziar says the GT 330M is a mid-range GPU that could be not enough for ur requirements. Another option is build the laptop yourself from site like Falcon Northwest and Sagernotebook

You´re right. I´m thinking about laptop. What GPU you suggest?
Thank´s

U could go with a GTX 285m or 5850m, both are very good GPUs.

Or even 5870M which is available in SAGER NP8690

or SAGER NP8760(17" version of 8690)

Thank you for the advice. I´ll try to see those

You are welcome  

Any time, that's why we are here. Focus more in the Falcon Northwest, have better quality and warranty.

That's a great notebook but IMO costs too much,Sager NP9280 would be a good alternative with same specs and its cheaper too

^Yeah, u are right. I test the best configuration for Falcon and I get an amazing $11,000 price.  

Get the i7 720, as it's a true quad-core capable of 8 threads at once, whereas the 620 is a dual-core that can handle 4 threads at a time. In terms of video editing and rendering, the CPU matters much more than the video card, as most editing software uses exclusively the CPU for these tasks. The ones that support video card acceleration often just support the high-end nVidia and ATI workstation cards. A lot of RAM, a big hard drive, and a high-res screen are also important for video work. Forget about those $4000+ gaming laptops; instead, look at this page on newegg with all their i7 laptops:

Then there's this ASUS model with an i7 720, 4GB RAM, 500GB hard drive, a full 1080p screen, and a GeForce 360:

It looks really, really good for $1200.

now,that's what i call priceless  

Yeah that looks good too,but for the same price the OP can get the Sager one with a 5870M which is more powerful than a GT 360M

Yeah, but I think that nobody needs 4 SSD 256GB   or the i7-980x in a laptop... 

What do you think about this one:
Alienware M15x: i7-720QM; 6 MB cache; DDR3 1333MHz 4096MB; 500GB 7200rpm; GeForce GTX260M 1GB; res 1900:900.
1600€

If you are going to get a M15x,then definitely get a 5850M instead of GTX 260M

^+1 I agree, the GTX260M was a very good GPU few years ago, but not today and not for ur requirements.

Go with the 5850M or two GTX260M on SLI.

was looking around. not sure if 5850 is GDDR5 or not in M15. If not then possibly 260GTX looks better option (despite the price tag)
