a few 7950 questions

post #1 of 4
Thread Starter 
Hello all, I've finally ran into some excess cash, and i figured whats a better way to spend it than a rig upgrade? so I'm considering going Crossfire 7950's and a 1440p monitor but i have a few questions, so any help is greatly appreciated, Thanks in a advance! biggrin.gif

1. How bad is this whole frame time issue that people wont seem to stop talking about? micro stuttering?

2. I've currently only got a 600W PSU, i'm assuming i'd need to upgrade that as well, wouldn't I?

3. any recommendations for a good reference board 7950? Wouldnt mind doing water cooling as the next big rig update that i have planned for sometime in late 2013 to early 2014

4. any reason i shouldn't go for a crossfire setup? 8000 series perhaps? any info would be great!

The goal is to handle 1440p with generally the highest settings I can get it to (AA excluded, i know its not really needed at 1440p)

thanks for the help!

I believe driver updates will fix microstutter.


as for the PSU I always go crazy overboard... I think 700 would be a much more viable option for 7950 Xfire, especially with that 8350.

At least 750w for a Crossfire Setup (CPU and GPU overclocked)

Micro-Stuttering is overly-exagerated BUT it is there. (for now)
AMD will fix this issue soon.

If you are not confortable with AMD, get GTX 660ti in SLI (or GTX 670 in SLI but its much more pricey)


309$ Comes with free Crysis 3 and Bioshock Infinite

REFERENCE BOARD and it can be watercooled with FullBlock ( check here for compatibility www.coolingconfigurator.com )

Thanks guys, +Rep to you both, switching to green team isnt going to happen, i already have one 7950 and am extremely happy with its performance, great card for the price! thumb.gif And microstutter will probably be resolved in driver updates, so i see no reason to switch teams here, I think I'll just go for it, get another 7950 a bigger PSU and a 1440 monitor biggrin.gif
