A few questions

1. Firstly, the related one:

I currently have an AMD setup:
X3 440
Asus M4A785TD-V EVO 785G
4GB (2x2gb) Crucial 1333mhz RAM
Sapphire HD 5670 (512mb) GPU

I run this on a 400w Corsair PSU.

If i was to upgrade to a 6670 GPU, and a Phenom II 955 processor, would you recommend increasing my PSU wattage?

2. Slightly off topic i know, but i really didnt know where to put this:

Would upgrading my processor and GPU allow me to stream video games like Starcraft 2 on a site like JTV with less framerate lag on my end? Obviously it will help, but how much of a difference is it likely to make?

3. With this potential upgrade, should i invest in an 'aftermarket' CPU cooler and more cooling?

Thanks for your help in advance! Any questions feel free to ask, and i'll do my best to answer them.

P.s. My PC is home built as of last August (2010)

  1. Seeing as i can't edit my post, i'll post it here:

    Currently i have 2 120mm fans, one at the back and one at the front.
  2. I don't think there is much power use difference between the 5670 and the 6670. I think they both use ~60W. The 6670 isn't much faster either. If you want an upgrade, go for a 5750 or 5770. All of these cards should be fine on a Corsair 400.
  3. Ok thanks.. What about the extra consumption from the 955Be and the 6770, for example?
  4. The TDP of the x3 440 is 95W. There are a number of different 955s, including a 95W version. If so, there is no extra power draw. Worse case is you'll get one of the 125W (they never made a 140W version did they???) and your system will use an extra 30W.

    6670 or 6770? As I mentioned the 6670 is rather close to the power numbers of the 5670, just over 60W. The 6770 has a TDP of around 110W, so if you use one of them it will use a lot more power. (50W) Worst case, 125W + 110W + 50 = 300W(ish). As long as your PSU has 25A you'll be fine. You really want one that has at least 28 to 30A so that you're not running your PSU at 100%. I don't remember how many amps the Corsair 400W has. Double check.
  5. Thanks man. Well i had a look on the website and it says
    +3.3V +5V +12V -12V +5Vsb
    20A 20A 30A 0.8A 2.5A

    I hope that shows right. To be honest i'm not really up on what all of these figures mean, but i can see that at 12V it runs at 30A so that's a good thing right?? :P

    p.s i hope the figures come out formatted right!
  6. It means of the 400W your PSU can output, it can do (12V * 30A) 360W on the 12V rail. This is important as its the 12V rail that powers your CPU, GPU, board, etc. I said earlier that you'd need around 300W, so your 360W should be fine.
  7. Thanks a lot for your time man, i appreciate it.
