Would it be worth it to upgrade to a 965be from a 720be with 4th core unlocked? - Page 2

post #11 of 15
My wifes pc has a similar setup to yours and hers is running a 720 with the 4th unlocked @3.5, my old 955 was running 4.0 and both had 6870s at the time, I was curious about it at then as you are now and most of the benchmarks I ran only showed a 1-2 fps difference which imo isn't worth it for the 80 or so you'll spend. 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.

hello,
your cpu cooler might do, but you would need some really great fans in push and pull and some even greater fans to pump air in to the case.

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.

Intake fans:
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.

Exhaust:
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.

Other:
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.

wish you the best.

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.

your oc'ed 7870 matched a stock 7970.

http://www.3dmark.com/3dm11/6328043

check out the physics score of the different systems. here is what you'll get when you go fx with just the 6300.

http://www.3dmark.com/3dm11/6444910

4.5 is quite normal for it.

anyway, the 8300 tops all these amd chips and will act the same way in the newer games but i'd recommend waiting for steamroller. if you can't, you should have enough info to figure out the cheapest path while waiting.

I suggest waiting for steamroller to hit the shelves and see what it has to offer. You may be able to get a much better performance jump.

I had a 550BE unlocked to tri core and then picked up a 955be for dirt cheap. the extra core helped, but that was about it. Don't waste your money on a side grade. Get an current 6 core CPU or wait for steamroller.
