What does FX-8150 mean for me?

post #1 of 47
Thread Starter 
I love my phenom II 955be a 4.0ghz.

I LOVE IT

The only problem is, is that I run 3 6970's, needless to say I am EXTREMELY cpu limited, pulling max 40% from all cards.

Will FX-8150 change things for me? Im not looking for more speed, im not looking for more processing power, Im just wanting to know will my cards still bottleneck on this thing.

If I can run 3 6970's w/o bottleneck, thats a 100% surefire reason for me to buy BD. It doesnt matter if it doesnt beat the Intel chips in performance, because I didnt need it to. All I need is for my CPU to no longer be a bottleneck on my system.

What do you guys think?

Uh, no. Single threaded performance went down. I.e. your bottleneck will grow.

Also, "Gpu utilization" is a pretty meaningless metric. If I'm seeing 40fps with 99% on one card, move to two cards and am now getting 75fps but only "60%" usage, what does that tell you? Now, we move to 3 cards and get 95fps. We're seeing 40% utilization. "Bottleneck" there may be, you are seeing real performance gains despite what some meaningless number from GPU-z says.

Also, V-sync. Turn it off. Watch GPU usage skyrocket.

You shouldn't have put so much money in GPUs though - on such a weak platform.

i5-2500K. BD would provide worse performance as mentioned above.

Is that with the new dx11 multithreaded drivers ?

I would get a 2500K, Bulldozer (imo) is a huge flop.

use MAX AA and check your gpu usage again xD

I don't care what settings he uses, that 955 is a huge bottleneck.

AMD is terrible for multiple GPUs, old news that hasn't changed.

I ALWAYS run 24xeq Edge Detect Super Sample AA, 16X anisotropy, triple buffering,no vsync max mipmap, max everything.All settings set to Improve instead of Override... Why do you think I have 6gb VRAM?

I understand I shouldnt have bought these gpu's on a weak platform, but I was really expecting better from BD.

An example, I can use the above settings on the witcher 2 and bull around 75fps in 1080p W/O ubersampling, ubersampling KILLS my fps down to 25....

You have 2GB of vram crossfire does not pool memory
