X800xt or the nVidia 6800 will do. My preference is the x800xt based partly on price and based partly on ATI's device drivers. They seem to be able to tweak more performance out …

I disagree - more RAM would do more. I have an early SP 1.8 G5, and things got noticeably better when I upgraded to 1.5 Gig from 500 Meg. Plus, it's cheaper.

I agree with the above posters about the video card, but I still would upgrade your RAM to at least 1GB. 512MB is the bare minimum and when playing a 3D intensive game like that y…

Why do you have to spend it all on RAM or all on graphics? I'd split it in half. $300 on RAM would get you an additional chunk of memory (2GB?) and the other $300 can be spent on…

The 9800 runs Doom III like crap on the Mac. You need an X800/850 or 6800 to get any decent frame rate. Shitty port...

Sucks to know that since it's the only game i've been looking forward to playing. I know i want a better video card than the 9800 and more than 1GB of RAM in my system. So far, i …

I'd think twice about this. I had a Dual 1.8GHz G5 with 2GBs of RAM and an X800 XT and Doom III ran like crap at 1024x768 with all the options off.

Oh well...I guess i'l spend the money on something else then. Thanks for all the input.

I was expecting a big performance gain if i had upped the RAM and graphics for Doom 3 but i guess not. Not looking to get jipped. So i'm not going to make the upgrade. Also, to do…

Cool. I will do that. Too bad on the Doom 3. I really wanted to make that game fly on my G5.

I think your real situation is the ram. Most game pauses are caused by paging, Warcraft III even pauses with less than 640MB of ram.

That's what i was looking to find out. Please give me some advice on how much RAM to put in my system if i wanted to have the absoulute best for my model G5. Will 4GB be useless f…

Crazy...I tought it was 4 slotted. I haven't actually looked in the machine yet so i wouldn't even know anyway. Thanks for the heads up. I've been very on/off about selling my G5 …

Just checked on the Apple site. My G5 does hold only 4GB of RAM, not 8. I guess you made a mistake. Would be cool if it did hold 8 though.

The latest version of the dual 2.0 uses the 4-slot motherboard, the earlier ones used the 8-slot motherboard. However, the G5 will recognize 2 GB modules, so the actual RAM limit i…

Here's the results graph that Barefeats got for Doom3 with the X800 (and one overclocked to X850 speed) on a dual 2.5 with 8Gb ram. Not actually very impressive compared to wha…

You're right, not that impressive but still good enough for me too. Pretty cool, i didn't know the 4 slot PM held 8GB of RAM.Can't seem to find 2GB DIMMS nowhere though.

No prob on the error. Those 2GB DIMMS are pricey indeed. Crucial do seem great. If i get RAM it'll most likely be from them.

I will say that RAM is your best bet, but also there is another option that hasn't been suggested yet. The best upgrade I ever did for my G5 was to get a Raptor 10K RPM HDD. A litt…

Yeah I think a 10k HD as my system drive will probably be my next upgrade... Barefeats to the rescue again.
