I honestly didn't look at the full details on your mobo but if a new mobo and cpu is out of the question then I would absolutely agree on the 1090/1100 route, my other suggestion would be a fx6300/fx8300 if your board will support it, might be a off the wall suggestion but if you can acquire a 960t that will unlock that is a great route also, even if it doesn't unlock its still a gem of a chip, I left mine run at 4.0 24/7 in x4 mode and it only took about 1.35v to do that if memory serves me correctly and the best part is they run nice and cool. Just my 2 cents, hope it helps
Wow... I didn't expect anyone come up with a direct comparison between a 720 with the 4th core unlocked at 3.5ghz just like mine and an amd 9xx CPU! That is really helpful, thank you!
Also thanks for input on the 1090/1100, they just keep sounding better and better and I will have to look into the 960t.

By great fans do you mean something like a Delta fan
(way to loud) or just a nice 120mm fan like an Corsair SP120 or Couger SF-v12h? I currently have a Thermaltake Armor Jr.
with 6 120mm fans in it.
Here is a description of how the fans are set up.
One on of these cheap fans
on the hard drive cage which I put into the 5.25" drive bay area.
One stock thermaltake intake fan.
One Corsair SP120 high preformance edition, I was going to use it on the hard drive cage but it made to much noise when pressed against that filter material.
Stock 120mm HDT-S1283 fan on CPU cooler
One more SP120 on the GPU cooler
One stock 120mm thermaltake exhaust fan on GPU the cooler.
Notes: I keep the speed reduction connectors on the SP120s to keep them from being too loud.
I'm thinking that I could get a cheap 120mm fan and use it to replace the SP120 on the GPU cooler then put that SP120 on the CPU cooler as a push fan and use the stock one as a pull fan. Would that be enough or should I get some more fans? For reference I don't really know what my current CPU temps are since enabling the 4th core disables the temperature sensor but with 3 cores at 3.6ghz it would only hit around 47c after a half hour of prime 95.
Thank you for that! I will have to download 3dmark 11 and run a benchmark.
Edit: This is the best score
I could get out of my system, only 7047 and that was with an overclock that is not stable for most games. I did notice that even my physics score changed a lot with GPU clock
, so a lot of the score difference could be because I only have a 7870 and you have a 7970. The score did give me the idea to look up what people usually get with a 720 x4
vs what they get with a 965
(remember to set only 1 gpu) but the scores are very random. Some people with their 965s at 3.5 to 4ghz and a 7870 at similar clocks to mine got a much higher score while some got a similar or worse score than mine.Edited by Rabid Guardsman - 5/28/13 at 11:54pm
