Hello, first time post for these forums and I have a question for you all, maybe you can help me figure this one out.

I currently have two rigs, one for myself and one for my girlfriend. Lets start with specs. Her system is running:

i7 2770k OC'ed to 4, 16 gig 2133 DDR 3, single 6950 GPU, 850 Watt PSU, 2 M4 SSD's in RAID 0.
not sure on the MB as i bought this system from a friend recently, not my build

My system
AMD 1100t x6 OC'ed 3.8, 16 Gig 1800 DDR 3, 2x 6950 GPU's (both at 16x)1000 Watt PSU, 7200 rpm SATA HD. Asus Formula V MB(not z)

We both play FFXIV together and we both get great frame rates. However her system seems to run "Smoother" than mine does, reguardless of equal frame rates. Is this just the simple fact of Intel vs AMD? And If I upgraded my CPU to a fx-8350 oc'ed to 4.8-5ghz, would It be on par with her system untill I can build my 4k system in a couple months? Any input would be welcome. Thanks!!

1. SLI/crossfire often has lower minimum frame rates than non-SLI/crossfire so 2X 6950 may have lower min than 1 x 6950. You could see that as lack of 'smoothness'. Your system should also see higher average frame rates.
2. AMD had some frame rate pacing issues with crossfire. You could see that as lack of 'smoothness'. google microstutter.
3. The single thread performance between a 4Ghz i7-2770 and a AMD 1100t @ 3.8 isn't small. That could be it. Does final Fantasy IV keep all cpus running hard, or does it keep them all running at low utilization or does it keep one high teh rest low ? (Resource manager and task manager both have graphs that will show this)

Suggest you play with one of your 6950's disabled and see how smooth...

Suggest you play with one of your 6950's disabled and see how smooth it runs. If dropping out of crossfire smooths it out then look at the newer AMD drivers with frame rate pacing.

Suggest (with both 6950s running) that you UNDERclock your 1100t and see if things stay the same or get worse. If reducing your available CPU makes the game less smooth then going to a stronger CPU might help. If reducing your CPU doesn't change anything, then adding a faster CPU seems less likely to help.

I did think at one time that it might have been microstutter issues, but it does not seem to be the case. I'm using the new drivers, as she is as well, and ive even tried running it with some radeon-pro settings to see if its one of those. Never the less the only was that I can get my game to run as "smooth" as hers is to run with extremely lowered settings. I guess it might be the per core application as you mentioned. I will nbe building a 4930k system soon with w/780i's so if that does not run smooth, im not sure what would. Ill take a look at the core usage when i get home tonight. That might tell me more.
