Thread Starter 
So I recently moved into a 2nd floor room from the basement. As you can imagine the ambient temperature is a lot higher. Now because of this I am considering upgraded my graphics card to reduce the amount of heat being produced by my computer. I've had the stock fan on it die and has to zip tie another fan on it, so I know it's running hotter than normal and wouldn't be surprised if it fails. I currently run 2 monitors at 1080, I often multitask (games + videos, multiple games). To be honest my 6870 does the job already for the most part. So the upgrade is not on a necessity of power. However I don't want to be throwing money away by getting a sideways "upgrade".

I've been looking at idle, load and TDP for each of the cards to try and figure out which is better for my situation.
7790 TDP 85W,
650 TI boost TDP 134W
6870 TDP of 151W (current card)

the cards are about the same price (maybe the 7790 is a bit cheaper)

Now my questions are:
1) Is TDP even a good measurement of how much heat will be produced?
2) Do watts translate in to heat uniformly across chip sets or are there some chips that produce less "waste" per watt?
3) Would fan noise be purely dependent on the manufacture? Any brand recommendations of either of the two cards that are very quiet.
4) Are there any other cards that are known to be better at producing less heat? I happy to hear of any suggestions.

There might be something that I don't know about so feel free to contribute anything you feel is relevant. Well that's all I can think of for now. If I can think of any more information I'll add it to the post/thread.

The 7790 will perform about the same as your 6870.

Out of the two I'd choose the 650 Ti Boost
