That's much better!

Your CPU will always be the bottleneck for gaming, which I assume you are looking for when speaking of GTX770/Titan?

I would not recommend going higher than the GTX660 you have now, since your gaming experience will be limited by the CPU.

Even now your graphics card are lot better rated than the CPU =)

If you're looking for gaming you should consider upgrading your laptop to a PCIe GEN2 one that can hold an Ivy bridge 45W CPU, like the 2570P that I use for instance see my signature.

This laptop can be bought for ~$600 on eBay with a i5 CPU that you can upgrade to a i7 3740QM for another ~$250.

TLDR: If you're looking for high-end gaming, consider buying a notebook with a better CPU.

I don't like gamming notebook since it's a big laptop and not mobile

I don't know which would be bottleneck in my system. As you know, I use GTX 660 non Ti and stilln't overclocked. And my CPU is intel i7 640m 2,8Ghz with turbo boost 3,458Ghz. While playing, I see the CPU will be constantly clocked at 3192Ghz

I'm planing buy a used vaio SVZ with i7 3612QM, but after see the spesification, that laptop is suck since no express card. And to use egpu, I need mpcie slot inside the laptop

Many Thanks for Nando4 and Jacobsson

After you gave me an advice, I bought immediately a 1080P LCD from conrad, and got a great result

here is my new result for 3Dmark 06 : 16410 and 3D Mark Vantage : 14093

NVIDIA GeForce GTX 660 video card benchmark result - Intel Core i7-640M Processor,Sony Corporation VAIO

NVIDIA GeForce GTX 660 video card benchmark result - Intel Core i7-640M Processor,Sony Corporation VAIO

may I ask a question to Nano4 : Is there actually any benefit to have a lower tolud..? Is a lower tolud can increase bandwidth..? And is there any performance gain if example I buy a GTX 770 or even the Titan compared to my GTX 660 in a pcie 1.1 .? perhaps 20 - 40 % maybe ..?

thanks for your help

Hi

yeah, may be will look around for a better external screen now

Do all your benchmarks using an external LCD. In addition, run Counter Strike on an external LCD. Those Z11 machines have a 1080P LCD so internal LCD mode consumes a significant portion of the x1 bandwidth. Using an external LCD, including disabling the NVidia sound devices ensures the x1 bandwidth is used exclusively for eGPU video traffic.

Hallo

thanks for the answer

yes, all the benchmark I did use the internal LCD since I didn't have external lcd

Hallo TI Expert

I have a little problem here with my 3D mark 06 and 3D mark Vantage score, and need your advice

Firstly here is my specification :

- Vaio VPCZ11C5E with i7 640M cpu HM57 Chipset

- PE4H v2.4 + Ec2C

- OCZ ZT550W PSU

- Asus GTX 660 ( Non Ti )

- The dGpu already turned off permanently through bios

I use this setup with my internal LCD, but the score from both benchmark always <10.000. The 3D Marrk06 result 9839, and the 3D Mark Vantage result 9704 as shown in this link :

NVIDIA GeForce GTX 660 video card benchmark result - Intel Core i7-640M Processor,Sony Corporation VAIO

NVIDIA GeForce GTX 660 video card benchmark result - Intel Core i7-640M Processor,Sony Corporation VAIO

I just don't know what happend, since Nando4 said, that if pcie compression engaged, the score should be minimal >10.000

And for this problem, I already know if the optimus is engaged with optimus tool ( picture attached )

Please help me for this problem and thanks a lot for giving your time ready my post

Additional : I Try playing counter strike global offensive with 1080p resolution, and any anti aliasing, or filtering disabled, and shadow quality very low, But I just get low than 30fps every time, and the cursor even a little laggy.

please give me advice, what should I do

Hallo TI member

I want ask a noob question

May be one of you already tred and succesfully use the egpu in SLI mode..?

I just think if this may possible, since I want a x2 configuration, but I just have port 1 for WLAN and port 3 for Express Card available. The port 2 is already used for memory stick card, and to make it free I must make a hardware level configuration, that not so easy to do

It may need 2 egpu adapter ( PE4H or PE4L + 2 HDMI Cable ), but it may be worthy to try, if the result would be great

thanks

Thanks a lot Jcagara08

I will test the system next week if I already got the psu

Hallo for all TI forum member

I'm a noob here. I already read almost a whole discussion here. But just to make sure, I want to ask directly from you

I have a sony vaio VPCZ1 series. The spesification :

Intel i7 640M processor dual core with hyper threading

Intel HM57 Chipset

Nvidia GT330m dGpu

Intel HD iGpu

Switchable GPU and static GPU from bios hack ( Nvidia off or Intel HD off )

Expresscard available

1920x1080 full HD LCD

And I just planning to make my egpu with Asus GTX 660 + pe4h v2.4 + EC2C. May be have you some opinion about my egpu. Will it working, and how about performance I can get with my system..?

eventhough the GTX 660 used pcie 3.0, I think it will be still some benefit use a pcie 3.0 Gpu on pcie 1.1 motherboard,

And because sometime I need to bring my laptop to university, is that possible, to activate the dGpu again without any problem..? I mean I want use GTX 660 and intel HD with optimus driver installed, but in same time I want instal the standard Nvidia driver for my GT 330M

Thanks for your help

and have a great day
