AMD Bulldozer FX-8150 3.6 GHz 2X Gigabite HD 7970's seasonic 850W PSU 1000watt UPS Asus Crosshair V Formula 16GB G.Skill 2X8Gb 1600MHz Noctua NH-D14 dual radiator coller 128GB SSD 1TB HDD NZXT Phantom Case 27" Asus LED monitor.
I still get lag when I play games on max settings. Im getting a intel i5 4760k. What I want to know was will the dual 7970s work fine with this mother board ASUS Z87-PRO LGA 1150???
And aslo I got a h110 liquid cool to go with it.and what do u guys this of this system???
The "lag" you refer to is undoubtedly micro-stutter. It is a well-known problem with dual cards in CF. AMD has been working on a driver fix for awhile and has just released the beta driver mentioned above: http://support.amd.com/us/kbarticles/Pages/AMDCatalyst1...
I just installed it on my other machine with 2 x HD 7870s. I haven't had a chance to test it yet, but the reviews have all been positive. Perhaps eventually AMD will have their frame pacing software embedded in firmware or hardware .
frillybob101, Seasonic is a very good PSU brand and is the manufacturer on contract for some other brands which merely resell them under their own markings.
Fayezrhaq, have you tried the Catalyst 13.8 beta drivers for your configuration to see if what you are noticing is reduced at all? I looked up the motherboard and it appears a perfectly fine choice. I don't think you could give your CrossFire setup a better infrastructure to run on.
That motherboard should be fine for any 1150 processor.
Has anybody bothered to ask the question, how much is to be gained by all the money spent on the new motherboard and CPU? This is a diminishing returns situation. You may not end up with as much as you are hoping for. It will be great for the future, but with your current cards, you may get less than anticipated.
How do you know your system is stable the way it's configured and overclocked? I never could get my FX-8150 stable at 4.6 GHz, even on water. :-)
Being a "gaming computer" is a relative term. While your system would be considered relatively high end, you can always go higher. There is no system on the planet that will ever max out graphics settings for newly released titles beyond the scope of time the hardware is designed for.
The other problem is "lag." That too is a relative term that needs more information to quantify what it actually is. Whether you're experiencing micro-stutter, CPU or GPU bottlenecking, USB input delay, or even delay due to the particular display being used, or even a placebo-like perceived "feeling", or for that matter, any combination of those, you're going to need to delve deeper to sort the problem out.
I can clock my chip to 4.6. That's not the problem. It's not stable under load for long periods of time. I can easily run it like that if I leave power management to clock the chip up and down. What good does that do me? :-)
AMD has their own stability test, and you can also run Prime95. While I don't see a problem with using Intel's test, I don't know if it's a reliable test for stability of AMD chips.
If you can't run Prime95 or AMD's test, it won't make much difference what Intel's test says.
What I'm saying is, you should be able to run any software, no matter what it is, if your overclock is stable.
