I’ll start. This was on a college student’s budget so my specs are improving over time as I upgrade.

Mobo: MSI P55-GD65 LGA1156
CPU: Intel Core i5-750 OC’ed to 3.95 GHz
GPU: 2x XFX Radeon HD 5770 in CrossfireX configuration, OC’ed
RAM: 4GB DDR3 G.Skill 1333
PSU: Corsair 850W TX with 70A on the 12V rail
Case: Antec 900
HDD: WD Caviar Black 640GB and WD Green 2TB

Favorite Games at the moment: Day of Defeat Source, Team Fortress 2, Shattered Horizon, Crysis.

My 3DMark06 score is a little more than 25,000. I haven’t run 3DMark Vantage yet.

I don’t really play many PC games, but my “gaming PC” is a Pentium D 2.8GHz w/ 2GB RAM (I think) and a GeForce GTS 250. I use a dual projector setup with polarized lenses/glasses for 3D with a modified webcam for head tracking. I haven’t found any games worth buying in many years, so I pretty much just play whatever demos can keep my interest for a few minutes… my favorite being Tom Clancy’s H.A.W.X.


Nice. How hard were the projectors to set up? I’m assuming you’re using 2x DLP’s then? What resolution? Does that require two graphic cards for video output or do you somehow daisy chain the signal? What kind of software/hardware do you use to split the image? I actually looked into doing that myself, but I didn’t like that a silver screen is required to reflect the polarized light, and everything seemed very finicky and hard to install, not to mention expensive. But I imagine it’s worth it in the end, right?

It’s actually pretty easy, and I did it for pretty cheap. I got the computer for $60, the video card for another $60, the projectors for $75 each, and the silver screen (40″) for $20 (all on Craigslist).

Then I used lenses from cheap linearly polarized glasses in front of the projectors to polarize the light, and of course wear polarized glasses. The projectors are LCDs (at 1024×768), though I’ve heard some LCDs won’t work… these don’t work with circularly polarized lenses. I just stacked the projectors on top of each other, and they’re pretty thin, so there’s not much angle difference, so the images merge well.

I just used one dual-head video card, and used the iZ3D driver ( http://www.iz3d.com/ ). I’ve been using demos of the drivers, though I’ll be purchasing it soon ($50).

Now that it’s set up, it’s really easy to use… just turn on the computer, projectors, put my glasses on, put my tracking hat on (for head tracking), and play 🙂 . Totally worth it 😉 .

I’m tempted to try one of these too: http://www.vuzix.com/iwear/products_vr920.html . The resolution is a little low, but if it works well, I’ll bet it’s still pretty cool.


That’s an incredibly good deal for projectors. I’ve checked craigslist and even the cheap old XGA projectors are going for hundreds, unless they are damaged/broken or don’t include bulbs.

So then the only content you view in 3d has to go through the PC? Could you watch movies with that setup? I have heard about the iz3d drivers but I don’t have much experience with them. Can you do any 2D-3D conversions of movies? I imagine most movies wouldn’t translate very well but some have potential.

Do you mind only having a resolution of 1024×768? I thought about buying a projector but I’m not crazy about hooking up my ps3/360 to such a low resolution for gaming.

Also, I looked into the VR920 and from the reviews I’ve read about it, they’re not very good. The manufacturer claims for those video glasses are ridiculous. They always claim something like “It looks like an 80″ big screen from 6 feet away.” But if you have tried them in real life, you know that it actually looks no bigger than a 19″ computer monitor that’s 3 feet in front of you. Plus there is no light blocking on the sides or bottom/top of the glasses so you have to wear them in the dark to get any kind of immersion effect. They would definitely be fun to play with but I have convinced myself that I would be disappointed with them.
