Hey, my first post, hello fellow commanders!
Outside of ED (here too I'm sure), I always hear people talking about how in order to use the rift, they will need a super expensive computer with giant-sized graphics card, while this may be true in some instances, I thought I would share my specifications and maybe give some people a little hope;
I'm using a Dk2 (I was late to the party and ended up paying $520 for one...)
I got an EVGA nVidia GTX660 refurb for $100 from newegg
An AMD FX6300 6 core "unlocked black edition", 3.5Ghz for under $100
A $40 H55 Corsair CPU water cooler
$50 600w Thermaltake PSU (I tried to skate by with a cheapo 1st = failure)
2x 4g Mushkin heat sink'd ram sticks
A $35 Biostar pooper motherboard for future SLI (When I find a cheapo 660

)
2x second hand 3Gb/s 7200RPM SATA hardrives in striped RAID
In the end, after buying a bunch of other, optional thing's like; a fancy case, super duper fancy retro game pirating capable DVD drive, fans, monitor, input devices, etc,. I think I spent between $400 and $500 dollars, and that's including a 24 inch IPS display.
I can run the game on the now-outdated IPS display with everything on ultra with no lag. More importantly, with the Rift, I can play with everything cranked up except for super-sampling, which I can run with the in game option at 1.5x.
I have never checked frame rate, though after almost 20 year's of PC gaming, I know what it looks like to go below 60 fps, especially with the rift...
The funny thing is, before I bought the game, I could only run the combat demo on medium... Just proves the dev's may care a little about optimization...
