Yup it is, even with 295s.
 
Just a note for you guys, if you haven't tried Max Payne 3, I really recommend it, it was an awesome game.

Well, had a few issues tonight but I did manage one decent run. I held about -45C for the duration of the run, it was tough to do since my dice comes in blocks, so I was hammering away before starting a run.
 
My first run at 1100MHz was the good one, I then did 1150MHz and got a lower score. I think that was because I didn't restart, just went right into it. After that I had condensation in the PCIe slot, some vaseline there stopped that, no idea how I'll get it out but whatever lol. I also had to up my insulation mid session too. I was going for 1200MHz next but I ended up running out of dice, I only got 8lbs to start with anyways.

Figured I'd check with my local Airgas. The minimum they do for LN2 is 180L, at $150.37 with fees. For dice they do 30lbs for $36.38, or 25lbs for $31.03. LN2 is pricey stuff lol, but that doesn't seem that bad.
 
Praxair is about $131.50 for 160L, about $50 for 30L. Again, not too bad, but their dice is more expensive.

Why don't you go to phase changing or refrigerated cooling? You can achieve your -50C temps and not ever need L2N or Dice. The initial investment is large, but in the long run you wont ever need L2N or Dice.

Not exactly true...LN2 is to see what is possibly your best case scenario on your parts.
Dice is for testing the water
SS is for maintaining a nice balance between the two, but a killer on the electric bill! Not to mention a Casscade.
 
And A SS can be quite costly to get fixed when broken. Unless of course you live next door to a SS builder.

@John, that's why I want to get versed in it and build a cascade sometime lol. 
 
Well I have college coming up and I only spent ~$200 so far on subzero gear. To be honest I'd love to run my CPU on phase at -50C 24/7, it's just not the best option right now.

 So is the board working?

a phase change is PERFECT for school, since you don't pay the electric bill ;)

Very true, so far I'm in at Florida Inst. of Tech. and Illinois Inst. of Tech., still waiting to hear from USAFA but we'll see on that one. So, I am actually looking into it. Not sure if I will just buy one or if I'll build, to be honest I'd probably buy one.
Although, aren't they kind of loud and they put out a lot of heat?

Not sure yet, all depends on financial packages and stuff right now.

Well if you will be using it at school and you are worried about the heat and noise i have a solution for you. Use a water cooled condenser and the school's water. I dont know what the default water temp is that is provided by your water company in florida, but here in Edmonton, the water is about 5C. Most water cooled condensers operation at a 85F discharge heat, so the delta temp is huge and makes for more efficient heat transfer.
 
Thats a good option if you dont have to pay for the electricity and water.
 
Plus, they have come out with DC compressors that are insanely effecient. They have SEER ratings of 28, which is about 3 times that of the ones from like 6 years ago (older ones have a EER/SEER rating of 7-10).
