Hi All

I have at the moment an Nvidia GeForce GT120 card in my Mac Pro.

Thinking of buying an ATI Radeon Hd 4870 card

I assume is this worthwhile :)
 
It will certainly make your energy bill jump a few steps. The 120 runs without any additional PCIe power where the 4870 runs on two additional six pin cables of 12V supply. I don't have numbers but be prepared to use 100 W more power and considerable more fan RPMs.
 
100W? Never ever. That might count if you are continuously gaming or running render apps that can utilise the GPU to it's fullest.

And higher fan speeds? According to your signature, you've got the card in your system? Did it change any of the RPMs of your system after you popped it in?
I assume not.

My Pro came with the 4870 any my fan speeds are as low as the pre-configured minimum, which is 600-1200, depending on the specific fan group.
 
I have both cards and have used the 4870 on and off in the last months. It makes my 2009 machine blow out a lot more heat when I have it in media server mode by night. It also hikes up the PCIe bay fan to cope with increased waste heat. I'm running a RAID card as well, so my PCIe bay isn't totally cold without the 4870 either. 100 W may be really a peak figure but it is certainly no negligible power difference. I would at least expect 50 W in idle.
 
ATI 4870 TDP is 225W
GT120 TDP is 50W

In OpenCL, the GT120 currently scores only marginally lower than the ATI 4870, whether this is driver issues or OpenCL's natural love of Nvidia's core structure is debatable. https://forums.macrumors.com/posts/8890758/

Very few tasks can actually leverage the GPU at this point, so unless you are gaming, I would buy the cheapest card possible to drive your display (GT120) and when software you use starts taking advantage of GPU processing, buy the best card you can afford at that time.

So OP... I don't think it is worthwhile unless you want to game.
 
Well, if your anything like me... I don't "need" the card and I'll probably never use it to it's full advantage, but I'm going to replace my GT120 with the GTX 285 anyhow! Maybe it will help in some areas that I use... Like iPhoto and iWeb, but if it's too much card for that, oh well, I'd rather have too much than too little! ;)

We're telling you, you won't notice any difference in performance, but since you cannot be stopped, be sure to spend on your Stepford Card for :apple:points!
 
I went for the GTX285.

Photoshop seems snappier and the few games I have can be set on max for all settings.

Also has the advantage of Dual DVI-I outputs though that depends on your preference to Apple displays

I'm running dual 24" Dell 2408WFP

Card was difficult to get in the UK though

Does Safari also feel snappier? ;)
 
So, say in normal daily computer use... Safari, Mail, iPhoto, iWeb, Pages, Numbers... Would you notice ANY difference between the GT 120 and the GTX 285? Even the smallest amount?

I just installed the GTX 285... I had the GT 120... iPhoto seems much quicker... Video/loading of Safari pages seems to snap a little quicker... Would this card have much to do with that or is it all in my head?

The GTX 285 does run faster, but it's overkill IMO. The HD4870 would have been nice too (maybe just as, or even better, as ATI's tend to have better drivers under OS X than the nVidia cards), and cost less.
