so which one of these models??i dont want anything else meaning amd or other brand because this is only i can afford....so which is the best for the money...i also have asrock extreme 4 3570k,xfx 550 or corsair cx 600, 8gb vengeance and NZTX lexa s....i'll be gaming on one 1080 only!!!for OC i dont know when its not serving me i will think about it
The GPU is cooled because the air generated by the fan blows through the heatsink. If the fan blows TOWARDS the heatsink there is still airflow. If it blows AWAY from the card the airflow is in the opposite direction but is still there.
So either approach either SUCKS or BLOWS.
There are a number of different approaches.
Personally I would concentrate on the following:
1) Company known for QUALITY (Asus, Gigabyte, Sappire Tech..)
2) Performance of the card (some are overclocked)
3) NOISE LEVEL UNDER LOAD (find an article/benchmark comparing similar cards. This indicates the quality of the cooling solution. There can be a trade-off but you don't want an overclocked card which does so using very noisy fans.)
*You also want to make sure your CASE COOLING is adequate as a large part of the graphic cards heat goes directly into the case. For NOISE make sure most or all of those fans can be controlled.
Many gamers forget to get a fan(s) for the FRONT of the computer to ensure proper air flow. Some cases have a fan included. I recommend one with 20dB maximum noise. You can get variable or non-variable fans. It depends on your motherboard as well. If in doubt, get a fan with a 4-pin MOLEX and run at constant speed. If possible, setup something like this:
- 2x FRONT CASE FANS (20dB each max, 500RPM to 1500RPM, 4-pin, controlled by MOTHERBOARD via BIOS and/or motherboard software).
The HD7970 is a good card. If the VALUE was identical (same gaming performance at the same price) then I prefer NVidia because of the following:
- TXAA (an anti-aliasing method which WILL be used by UNREAL 4 and others for more efficient anti-aliasing)
- GPU BOOST
For many these features are not that big a deal and VALUE is more important.
*PRICES and VALUE are always changing between AMD and NVidia. AMD recently had the HD7970/50 cards offering THREE GAMES included. I think that's still going on.
I know the GTX670 has TWO good games included.
- compare BENCHMARKS and PRICES to determine value
- compare FREE GAMES
- ensure quality BRAND (Sapphire Tech, Asus, Gigabyte)
- ensure good COOLING SOLUTION
- *If the HD7970 card (i.e. Sapphire Tech) you find is a better VALUE than a similarly performing GTX670/680 then go with that.
