Video Card upgrade for early 2008 MacPro

Did you have to flash it at all? Or just straight up bought it and put it in?

Where did you buy it? And which particular one did you buy? I see lots of different GTX 750 ti out there.

On non-flashed card will not display anything on the screen until drivers load. That means the special startup key commands that require viewing the screen do not work. Examples are Option key and Recovery

Yeah I get that, this thread goes into detail on that pretty well. But just wondering about the 750 ti in particular this thread doesn't talk a lot about that one.

And I have mac pro early 2008 10.10.3 just like Caurina above. So was curious about the details my local MicroCenter has this one for 150 which seems pretty good to me. If that's a decent card for my Mac I'm going to go up and pick it up today.

Gigabyte GeForce GTX 750 Ti Overclocked 2GB PCIe 3.0x16 Video Card

It appears to work. See:

hi EVGA GeForce GTX 750 Ti https://www.evga.com/Products/Product.aspx?pn=02G-P4-3755-KR

Update 12-15-15

El Capitan versions 10.11.0 and 10.11.1 had not worked properly with the graphics card and the machine (Mac Pro 3,1 from 2008) wouldn't boot.
I installed 10.11.2 and the machine is booting properly, and is stable with an absence of problems using the GTX660Ti card.

Here is an update for anyone who is interested: It has been 24 hours since updating and the Mac Pro 3,1 has become almost totally unresponsive twice under 10.11.2. The first time the computer became unresponsive was after I highlighted a PDF on the desktop when Mail was open. The second time was when I was running an app named Wiki. Mail was open (and minimized) and Firefox was open also. While searching for a piece of text in the Wiki app, the computer became almost totally unresponsive.

Here is what I see: The dock disappears from the bottom of the screen, and when I open the Force Quit Application window, the window becomes unresponsive. I can use COMMAND and TAB to switch between apps, however even after the app name changes in the top left of the screen, the apps won't respond to keyboard or mouse commands.

I can move the mouse, but clicking does nothing at all. The only option I have left is to press CONTROL, OPTION, COMMAND, and SLEEP to restart the machine. When the machine restarts it seems to work fine.

I ran disk utility in El Capitan to see if there were any persistent errors, and discovered that Apple has removed several options from the latest version of Disk Utility and now leave users with a unhelpfully-simple First Aid option only. Unfortunately, when the computer becomes unresponsive, I am unable to open Application monitor, but will keep it open to see what appears when and if the computer does the same again.

Update at 12/20/15: Finder has been partially unresponsive at times, and I have had to revert to Yosemite 10.10.5 which was a stable build for my machine.

does a macbook 2008 PCI

have a slot for a video card?ℹ

No. The graphics unit is soldered to the logic board

Ermmm no...the MacBook would have a graphics unit soldered to the logic board.

A Mac Pro Tower computer has expansion slots for the GPU card(s)

The Mac Pro does not have 'in built/ onboard graphics" the GPU on tese machine sis definitely card based and can be swapped.

I have just fitted a refreshed nVidia GTX780 3GB 4K card to mine replacing the two original 256MB ones, so now I can run 4 screens off of one card instead of two cards

Wow! I am a professional word-smith and I have absolutely no idea what you are saying.

I too would like to upgrade from the ATI Radeon HD 2600XT on my MacPro (early 2008). Could the NVidia GeForce GTX 770 work on an El Capitan system?

Can someone explain in more layman terms, You are so intelligent , i just need to upgrade my graphics card on a late 2008 silver macbook or aluminum so that photoshop will work and this is such complicated information.. I replaced the hardrive and the ram, and the battery . There is a disc in side when you open the back but I tried getting 1 Tigabyte disc and got another square hard drive.....

They said i may be unable to get 3d graphics and to upgrade some card. I get it a 2008 is a dinasour and I have a newr ipad and an iphone 6s but a new laptop I cant afford and my cards can't afford to buy what I dont need so if Someone can recommend a NIVIDAD CARD or what , I can possibly get a Credit card but Im not gonna waste more money on a plug in or replace anything ... I shoulda got a working ddll or something that was affordable but I thought The hard drive would be the anser , and I ended up in a money pit

You are on the wrong forum.

This is for the Mac Pro..NOT the MacBookPro. The Mac Pro is a totally different machine , a big tower box like a normal PC ( but better built )

But from my limited knowledge of the Mac laptops YOU CANNOT change the graphics card..it does not have an actual card, the chip is part of the main board.
