Mine:

Sometimes run at 1200mhz core with 7ghz on the vram. Though to be honest they could go a bit higher but these days they are back at stock speeds.

I have 120x2 and 200mm rads. Nice and quiet.

MSI radeon hd 7750 2GB DDR3. I'm Getting this at some point http://www.amazon.co.uk/XFX-Radeon-Edition-Graphics-GDDR5/dp/B00HHIPM5Q/ref=sr_1_1/275-6140558-1902837?ie=UTF8&qid=1407923116&sr=8-1&keywords=xfx+r9+290

Nvidia GTX 770 it's beast with a huge silent 3 fan cooler.
Never been so happy with videocard since the Ati Radeon 9800 Pro days.

Asus Radeon HD 7950, I like AMD =)

[sebihepp]

I have an AMD R9 290X from Sapphire TRI-X and are very happy with it.

Loads of them, 780ti X 2, 770 X 2, 680 x 2 , Hydro Copper 2 Water Cooled 580s x 2, 560ti x 4, all run in SLI mode, and Quad x 295 GTX, few others not mentioned, they all work well with Intel 4770k CPUs, and flashy lighted RAM. 1 TB SSds, Max performance, and big 1500 watt PSUs, Windows Experience 7.9, my problem, is Benchmarking, futuremark, I do not have access to dry ice and liquid nitrogen, to cool my sytem, during overclocking, one day.

Clearly minted and know yer stuff but I have slight bad news - I heard you cant N2O your rig for that purpose (i.e gaming) as it is used up quite fast and is dangerous and requires constant care and knowledge. You might also experience a cold bug where the sensors and capciators fail and dont function. It's also, as its generally used - to benchmark and freezing components at a temperature that low so they can OC to insane amounts.

Also you need to grease the board a LOT of times to prevent the condensate from touching the electronics that are turned on and it cannot be closed. The reason is because if it gets warm and cold very fast, it can explode. Yes, EXPLODE. An embarrassing story to tell to coolers every where how you got that scar. Haha - joking of course!

Unless you have a refrigation system that recondenses and keeps the pressure of the components at constant, cool temp you'd pay through the damn teeth for it. You might be able since two 780 ti's is generally an rrp of 500-700, so consider highest price of £/$1400. You'd probably be paying at least a couple of grand for it.

You should go for a phase change unit, cascade, dry ice (DICE). Phase Change is essentially air conditioners in your PC. Cascade systems which are different from single stage, which is basically an air conditioner but replaces the evaporator and the block on the cpu. These are more expensive but cool efficiently more than the single cooling methods like water chilling or phase change. Also they are incredibly loud and use a lot of electricity so expect massive bills.

Though you wont achieve the same as N20, you will still cool it down to really cold temps and get good OC's on sensible vcore voltages. Also its available by many computing retailers. An explanation from overclock is as follows;


Phase-change cooling is an extremely effective way to cool the processor. A vapor compression phase-change cooler is a unit which usually sits underneath the PC, with a tube leading to the processor. Inside the unit is a compressor of the same type as in a window air conditioner. The compressor compresses a gas (or mixture of gases) which condenses it into a liquid. Then, the liquid is pumped up to the processor, where it passes through an expansion device, this can be from a simple capillary tube to a more elaborate thermal expansion valve. The liquid evaporates (changing phase), absorbing the heat from the processor as it draws extra energy from its environment to accommodate this change (see latent heat). The evaporation can produce temperatures reaching around −15 to −150 degrees Celsius. The gas flows down to the compressor and the cycle begins over again. This way, the processor can be cooled to temperatures ranging from −15 to −150 degrees Celsius, depending on the load, wattage of the processor, the refrigeration system (see refrigeration) and the gas mixture used. This type of system suffers from a number of issues but, mainly, one must be concerned with dew point and the proper insulation of all sub-ambient surfaces that must be done (the pipes will sweat, dripping water on sensitive electronics).

More on cooling; http://www.overclockers.com/an-introduction-to-extreme-cooling/

And condensation protection because when it starts to... well...melt or condensate, say goodbye to the components. - End of Pahse Change Unit





Also a closed system of N20 is not possible as the expansation and contraction of the cooled components could (operative word; could) potentially explode and break plastic parts as they become very brittle as extremely low temps, they also condensate and are unsuitable for long gaming. Supreme at overcloking and benchmarking, I've heard an I7 4xxx series of cpus have been oc'd to 7 GHZ. I heard one world record reached 10 GHZ. It was one of Intel's articles I think.

Sorry if I am typing a LOT.

Might edit my comment to correct information so... dont call me out.

Read every word over and over, mAGNUSwAKER, thanks for the info.
