Dell XPS notebook , can't decide

pls help me to decide.


new xps 15 rgb 1080p with GT 540 or xps 17 3d 1080p with GT 555

also i7 2620m or i7 2630qm or i7 2720qm

as a replacement desktop in view to playing med-res games, some multitasking and maybe video editing.


I understand the i7 2620m has a higher clock speed and actually costs more than the i7 2630qm quad core, is this going to be better for my use? or should i spend more and go for the i7 2720qm?

Is the GT 555 that much better for games (maybe i can get some high-res games usage aswell) than the GT 540?

Is the 15" RGB screen that much better than the 17" 3d improved wled?
I could still use the 15" RGB screen for 3d games if required on my 3d tv.

 

Well, getting the 15 is a smaller screen, and the 540 is 1GB of dedicated graphics memory
The 17" is a bigger screen, but you have 3GB of dedicated graphics memory to handle it.

For Gaming, the 17" would be pretty big, a 15" is perfect
For Videoediting, i'd go with the 17, since you have a bigger screen to work with

2620 has a higher clock speed, but I wouldn't advise it. It has a higher clock, but its only a dual-core processor. the 2630 is quadcore, and might be better for your type of work.
Between the 2630 and 2720, i'd say it's your decision. How much are you willing to spend?

The only difference between the 15" screen and the 17" is that the 15" is smaller (obviously) and the 17" has 3D capability.


Personally, I'd go with the 17" because more ram fits. ^.^ and You can have dual HD's if you so wish

 

The heavier your multitasking and video editing and the very latest games at full resolution/detail, the more you'll benefit from even as slow a quad-core as the 2630M.

There's a running argument between me and a couple others on here about this. I think that if you do those things relatively little, then you might be better off with the faster dual-core. But we'll really need to see full comparisons to really be able to tell where the trade-offs are.

The 17" 3d screen (and currently only way to get 1080p on that model) disables Optimus, so your battery life would be shot with that model.

Screen size doesn't matter, only resolution as far as the video card goes.

 

Which is what I was referring to when i said that with the 17", you have a 3GB to handle the increased resolution compared to 1GB in the 15". Sorry if I wasn't clear. Or if I'm just spreading misinformation. I'm new at this. xD

 

The 15" has 2 GB of memory. And DakkonA is right, it is resolution that matters and they will be the assume you are upgrading the display on both models. As for GT555M vs. the GT540M, it is kind of like quad-core vs. dual-core: the GT555M has more pipelines but runs at a slower clock rate. The GT550M is actually running at the faster clock rate even though it has only 1GB to work with.

The extra pipelines at a slower clock speed result in really attractive benchmarks, but I haven't been paying enough attention lately to know whether that actually translates into legitimate game performance.

 

Correct me if I'm wrong, but it's only the resolution (# of pixels being controlled) and refresh that really matter -- the screen, be it 15" or 17" shouldn't make a difference.

If you run a 1920 x 1080 15" or a 1920 x 1080 17" or even a 55" 1920 x 1080 TV, the load on the GPU should be the same.

 

Actually now that he rephrased it, it makes sense. He wasn't saying that the screen size matters, but that in the 17" model you have more graphics memory available, meaning that running a game at 1080p on the 17" should have better performance than 1080p on the 15" due to the extra memory. However, as LoganK pointed out, there are other differences between the 555M and 540M that could matter more. It's possible that the extra RAM only is necessary for games playing in 3d mode, where it needs to push twice as many frames to the screen for smooth play.

 

No, even the rephrase didn't make sense, because there is no increase in resolution, only screen size.

"you have a 3GB to handle the increased resolution compared to 1GB in the 15"."

The two screens are both 1080p. Yes, having 3GB will be an advantage on like resolutions.

17" or 15" is non-factor. There was never mention in the OP of different resolutions.

 

if u ok with 17 then definitely L702X--- 1080p, GT 555M, 2630QM (or higher quad if u want to spend more but no dual core)..... i guess it isn't that complicated...

 

FYI, don't confuse the L502X B+RGLED panel with an RGBLED panel. While the B+RGLED panel is better than the average WLED, it is not an RGBLED (which uses 3 separate LED's to make the white light).

Also,
The GT 540M has 2GB of dedicated memory when the L502X is configured with the 1080p B+RGBLED panel.
