View Full Version : adding a video card via thunderbolt

01-02-2013, 04:55 AM
Ok so I have the g75vw-bbk5. I have read that the thunerbolt port on this model is a true thunderbolt port. I was wondering if it was possible to get a thunderbolt -> PCI adapter and add a dekstop gpu to the system. I am aware that it will require it's on power supply and I am fine with that while I'm at home. My question is, is it possible? How would I go upon it? Would i need a vbios for the new card? Thanks guys.

If this can be done. I also want to connect a gpu to my VX laptop.

I am not writing a full answer since i am on iphone...you need an adaptor like MSI GUS II. Google for details.

Edit: i didn't notice "g75vw", i thought g75vx since we are all busy with this new machine @ our labs. You cannot put an external thunderbolt vga on g75vw because it lacks intel thunderbolt hardware. You can do it with g75vx only. Sorry.

No G75VW's contain Thunderbolt hardware sorry. Only the newer VXs have the option.

thats unfortunate.. i read somewhere someone said the bbk5 had real thunderbolt after a certain manufacture date... because i have the 19020x1080 display and his hadn't... but ok... on another note, if I'm not worried about voiding warranties are there any more powerful cards than the 660m that I can put in here?

and yes I will be overclocking it so keep that in mind. It has to be more powerful than the 660 overclock vs overclock as well

You can purchase a 670M off ebay for the G75, but it does not come with the heat sink. http://www.ebay.ca/itm/Genuine-ASUS-G75VW-VGA-Video-Card-60-N2VVG1200-B23-/370703425184?pt=PCC_Video_TV_Cards&hash=item564fa55ea0

i thought the 660 can overclock better than the 670 resulting in better perfrmance, no? the main reason i ask is i play natural selection 2 and the 660m can not go high on everything evern when i overlcock it ... core clock currently @ 1250 mhz and shader clock @ 3000

A 660M OC'd is almost equal with a stock 670M, despite only having 128-bit vs 192-bit. Overclock vs overclock though, the 670M is much faster, anywhere from 5-10fps more than a 660M.

wow so youre saying i could go higher than 1250 and 3000? would a gtx 670mx work as well?

01-02-2013, 09:18 PM
also, will any gtx 670 i buy do or is there a specification i must follow for the g75vw

No, it has to be by ASUS as they have made their own MXM PCB. It's not a standard MXM you'd see in Alienware or Clevo's. If you try custom fitting one in, you run into trouble with heat sink and mounting, portability, bios unlocking, and overall stability issues.

At 1200 core clock at even 2800 mem for a 660M, puts it near level of a stock 670M - but the memory bus width is where things don't look the same on-screen. With the 670M, you won't get the slow downs you get with the 660M due to the memory bus bandwidth being higher, this in return keeps the avg fps longer as well as overall fps higher, despite what benchmarks show. Most of the benchmarks out there were using the initial drivers when the G75VW was released. So I don't go by those.

If you wanted a better video card, you should have went with the MSI GT70 that has the 680M in it already. I really hate the look of the GT70 compared to the G75, so that's why I made my choice.

But that's not what you want to read.

The demand has to be there for ASUS to allow purchasing of these kits for our G75's. If they want me to sign away my SN so I can't return my laptop if something goes wrong, fine, just give me the option to upgrade cards.

Thunderbolt will be bringing benefits in the future and will make the portable solutions more powerful.

But as of today no one should really cry over thunderbolt since the solutions for addon graphic card are so expensive that you would really consider buying desktop over thunderbolt enabled laptop and addon solutions for gaming.

@dreamonic thank you very much for your help and insight and lesson... on a seperate note i got teh g75vw for 750 with a year warranty from best buy for xmas--can't beat that haha... all i gotta do is spend a little of my own money to put in the 670 got quoted at 560 for card+labor... would do it myself but i heard they need to tweak the cooling or something of the sort... might wait a little til the prices for the card drop a bit though

@gokica yes very true i was just hoping that 1. what i read about me having a thunderbolt was true and 2. id be able to utilize it by adding an extra gpu and calling it a day... but yea a desktop would be much better in the end. thats the next thing i am aiming for :)
