I wish you all the best and I hope someone smarter than me can help in your other thread.

got my PSU today and all set up, so now im just waiting for GPU which should be here tomorrow. i had a cool idea for the enclosure. im going to do a plexy glass box with the PSU and Gpu in it, and have a big fan with blue LED's on the top and some holes on the sides for exhaust.

I think UV reactive Plexiglas is available, that would look cool. It also glues together easily with a liquid glue.

kinda going cheap on this. simple plexi and screws. i spent way too much already lol. but NEW GPU COMES TODAY!!!!!!

got everything working, and all is awesome! havent played a game tho, b/c i got home too late

running even better on BFBC2 but still lags like hell in all my DX9 games.

so although installing the other internal GPU driver helped in all my directx 9 games, it really screwed up the directx 11 games. performance like droped 50% in those. BFBC2, i can no longer play on 1080 with high settings. more like 1024 with high settings? dafaug? lol this is annoying.

so im trying a GTX 560 Ti and still have the SAME problem.... any ideas?

*UPDATE*

ok so i figured id give you ppl a little update on the eGPU build....

so far, im still stuck on the lag issue. its come down to 2 things.

1) my eGPU is incomparable with my internal gpu causing lag on some games.
2) only running at PCI 1.1 x1, some games do not like this speed/ combination hence why Dirt 3 and BFBC2 run amazing, but others do not.

ive ruled out it being the eGPU itself, because ive tried 3 different GPU's. the original 6670, 6770, and GTX 560 Ti OC.

im not currently running the GTX. it has givin me some better performance, and compatibility.

***im selling the 6770 is anyone is interested! please PM me for more info!

my solutions to the above problems is this:

1) i need a program called Setup 1.x to completely disable my dGPU (internal gpu) pre bootup to windows.
2) i need to get another mPCI adapter and cable to create a PCI 1.1 X2 setup speed.

i am confirming this before i go buy anything else, and will report back my findings. however, having reading 1000's of pages on forums, the X1 speed is known for amazing performance in some games, and harsh performance in others.... soooooooo i might be on to something here. unfortunally, first gen intel CPU's dont support PCI 2.0 or 3.0..... so i think my next laptop will be one with a 3rd gen core i and both express card and mPCI slots to create PCI 2.0/3.0 x2+ speeds lol

First of all, I looked up dell studio 1458 and there are several variants.

All of them have this fun feature (sarcasm): shared RAM; which means the RAM is used as video RAM too, that tells me the basic architecture is going to probably NOT be well suited for this endeavor, it's that big a performance hit, already.

Just my initial reaction to it, always advise avoiding shared memory PC/laptops, performance hit is ridiculous versus same without, when you get to pushing the limits as direct-x gaming does.

yupp its it s confirmed that i will need setup 1.x for that reason.

alright well after a lot of testing, m stuck at PCI 1.1 x1 speeds due to restrictions on my laptop. so it is what it is. if i have a PCI 2.0 compatible laptop, i would not have lag issues, but owell you can only get so good. so now the only thing i can do is Overclcock my FSB. thats all. my other options are to get another laptop. which is not happening lol. so for now, build is done.

i wil post a conclusion in the OP later tonight and also update the intro.

 

[Quadrider10]

ill finish and review the OP later but for now, build complete

 

[Britton30]

It's been a helluva project, but I'm happy you have it going now. now on to build some type of enclosure for the eGPU?

as much as you will hate me for this, naaa im not. 1 i spent way too much money, and 2 honestly i dont need it. i have it taped to a flat surface on my desk. its not exposed to electric and it cant get knocked off.

my next laptop it i get one is going to be a pci 2.0 or 3.0 compatible with dGPU. basically now i spent enough to build a basic/decent gaming computer. i spent about $400 in total with all the stuff i bought. rite now all i need to complete a desktop computer is keyboard, cpu, ram and case and mobo. i have everything else lol

What's the performance like? Worth the effort?

read the "conclusion" from the OP. i explain everything there.

BTW i have a 6.1 graphics score in WIE

 

[Quadrider10]

alright so the op is finally updated and true. Enjoy!
