Doom 3 Buyer's Guide

Memory for Doom 3

From all the comments that have been posted, there seems to be the unquestioned assumption that more memory will improve Doom 3 performance. The reality is that we have not been able to confirm objectively that assumption. The built-in benchmark for Doom 3, accessed from the console, was used to test common memory amounts on an Intel 875 platform, an Athlon 64 Socket 939 platform, and an A64 Socket 754 platform.

It was surprising that there were no real performance differences between 512MB, 1GB, and 2GB of memory in our benchmarks with the built-in Demo1. The only memory amount that shows lower performance is 256MB on the Socket 754 platform.

Perhaps the built-in Demo1 does not stress the system enough to really reveal performance differences in total memory. We did check memory usage in the console and found Doom 3 used memory up to about 1.5GB if it was available, so we are puzzled why smaller memory amounts did not impact measured performance.

We are looking for more sophisticated methods to test the impact of total memory on Doom 3 performance. For now, the best we can say is that 512MB or higher seems to be effective. If you have 256MB, upgrade to 512MB. We can also say from a purely subjective point that a Doom 3 system seems more responsive with at least 1GB of memory. Loading Doom and switching back to the screen is much faster with 1GB than 512MB.

    #21 - A recent storage article said there was no need for RAID on the desktop. It did not say there was no need for Raptors. In fact the title of the first article using the new storage benchmarks was "WD Raptors vs. the World"

    On another note, you just had an article a while ago saying that there are no need for Raptor HD's on a desktop system, yet you recommend it for the performance segment. May I ask why we should waste $175 on this drive when you yourselves said we had no need for it? Especially if the main goal of this rig is just to play Doom 3.

    I'm most definitely complaining about value, not crap. Mainstream Doom 3, while higher than general, is definitely not that freaking high. Who would buy a Dell for a GAMING system? This guide is for those who BUILD there own, so Dell has absolutely nothing to do with this, nor do their horrendously expensive computers. For a mainstream Doom 3 experience, a 6800GT was quoted as being required. This is a $400 card that allows you to practically play the game at 16x12 with AF and AA. Are mainstream Doom 3 users going to run at this setting? No. Even the value recommendations will run Doom 3 at 12x10, no sweat. Value should be those looking to play the game, but not having to spend much money and not caring about high res and eye candy. This is why I dissagree with the recommendations and pricing. If you think I'm wrong, that's your opinion and I could care less. My own personal rig was about $800 with the monitor included, and it runs the game at 10x7 on high detail. I'd consider that more mainstream than what the value recommendations would get you.

    May I ask what the point is of having a 12x DVD burner on a mainstream system devoted to playing Doom 3? And by the way, I agree with #1...this is just too much hype. Who would spend $1900 so that they could get "mainstream performance" on another $50 purchase?

    I agree with the CRT recommendations over a LCD. LCDs are coming to amazingly low response time, but I don't think I have ever seen one as good as a CRT. Good recommendations though. Maybe a 5900XT would be an even more value alternative, as I thought if I remmeber correctly it performed alright, overclcoekd a lot on average, and is pretty inexpensive.

    It is pretty amazing that you can buy such a powerful system with such a fantastic video card for around $1000. Things have come quite far in such a short time.

    Good enough article, a few typos, but helpful. Still kinda hurts to know that even the value system recommends needs a new (almost next) generation video card, but I can't argue with the value price. $1000 for a pretty good system is quite acceptable.

    It's a minor correction but you mention that the Chaintech VNF3-250 doesn't have GbE (correctly) in the article but in the table, you mention it has onboard 10/100/1000.

    Good article, I just wish I had $1000 to be able to play Doom3...

    #10 - We had technical problems with posting today and I did not get to make final changes as usual before the review posted. In fact the Performance system does now have a 2GB memory recommendation since we finally found 1GB dimms that could still give us 1T Command Rates with timings that were still pretty decent. The Guide has been updated with the 2GB recommendation, the revised price, and several other planned edits.

    So looks like I'll be playing Doom3 around April 2005...Its been 10 years since Doom 2, so whats another year.
