what do you think of that installation for gaming?

http://forum.notebookreview.com/7718053-post4504.html

he used DIY egpu installation via a ExpressPort 34mm!!! quite impressive! he used a desktop GPU the 480 GTX! i think it's a good gaming rig! what do you think?I feel comfortable using this installation! but the processor has a big importance in term of performance, right?i mean if an outdated laptop having an expressport34 with an outdated processor having that DIY installation will not have the same performance of that vaio!
i think this installation would win 1n m17x r2! it will be more powerful in term of performance! ideas?

Why nobody used that installation on an m17x R2 since expressport54 is built in the system? even if it has high end gpu's (amd xfire to sli) why nobody tried that installation?

 

Depends on the game. In any case you'll do better than any dedicated GPU in a small laptop. And why didn't you post in that thread instead of making a new one?

 

Personally thats quite cumbersome and if I am going to use it on a desk, I'd rather build a full fledged desktop rather than trying to make my laptop a desktop.

And yeah laptop CPUs are nowhere near the power of desktop CPUs in the same price range.

It's a fun idea to try and if you are crippled with a lower end integrated graphics, well it is valid to try that setup, but otherwise I wouldn't even try it myself.

 

Newbie question...This eGpu can be used on all laptop models? What is the special hardware one has to buy to fit an external VGA to a laptop?

 

you need an expresscard slot on your laptop. that gives you a 1x pci-e link iirc. Normally, a graphics card gets much more bandwidth, but the whole point of the eGPU is a compromise on performance, cost, portability, to earn you the convenience of having only a single computer.

 

One thing that's not very good about these eGPU solutions is the bottleneck.

Maybe long time ago when systems were built as a package and everything running at same speeds.

Today everything is modular. CPU, GPU, Memory, HDD everything running at different speeds and this leads to bottlenecks.

It makes little sense to have GTX 480 when you are using a really slow CPU from that tiny notebook. CPU will be a massive bottleneck to that GPU.

So yes, I still think if you want performance from GPU, you need performance from CPU. If you have the new i7 2nd Gen Sandy Bridge, go for it. If you don't, then pass and just buy a Clevo with a 580M and I7 2nd Gen.

 

You're describing a time that was not only very long ago, but also in a different universe. Computers with dedicated graphics cards never existed in single-speed computer systems. The whole point of having any graphics card is to have hardware doing fast calculations separately from the rest of the system.

Before modular computer subsystems existed, there was no concept of a graphics card.
