please forgive me if im repeating something someone else has already spoken of...this is my own experience (and even though i build my own computer systems, im a low end hardware guy)
as most of you will know, i have tried and failed miserably with the amd 6100 bulldozer processor on a FXA 990 board.
i believed the marketing and purchased without having first waited for someone to waste their money do the testing.
Anyway, i wish to also add, that since my upgrade to an Intel board and 2700K processor i have been able to look more closely at the Radeon and Nvidia cards. There are two areas i have studied...scenery quality and eyefinity.
1. scenery quality
The Nvidia card in my view definately produces the better quality imaging...and it is very noticable when you move the textures settings into the high range. I found it almost impossible to get rid of the pixel type lines visible on the horizon and landscape with the Radeon card even when on maiximum settings in prepar3d. Those same settings with the Nvidia card installed produced near photo quality imaging that absolutely blew me away! It is the first time i have ever been able to experience an environment the same as the photos i have seen on the net of the simulator running.
My understanding was, eyefinity allows the GPU to take on the role of processing for multiple screens in a way similar to matrox tripple header. I mean after all, the 3 screens i tried this on are all connected to the GPU card directly.Now, with that thought in my mind, i then went out and purchased the "active display adapter" and set up 3 monitors thinking this thing would burn just like my fathers 2600k does running a matrox triple header running more than 6 monitors (i cant remember if he has 8 or 13...theres a lot anyway!)
Now for the outcome...FAIL!!! !!!!
The system was crapping itself trying to even run prepar3d let alone display 5000 odd pixels wide by 1080 high! I have no idea whether its because the Gigabyte Ati Radeon 6970 simply is a poor performer (one would be a brave man to make that statement in the wider gaming community ) or, perhaps prepar3d is not able to make best use of the abilities of the card processor at the moment.
Anyway framerates, with eyefinity enabled and display resolution spread across 3 x 23" 1920 wide x 1080 high screens, dropped sharply (to the point where one wouldnt even feel himself able to drop his strides in public and be measured )
I tried fiddling a little (pardon the pun ) with Catalyst control centre settings in order to move more of the graphics processing to the card, all to no avail. These merely reduced the image quality ingame and from what i could perceive, did nothing for framerates.
This experience leads me to believe that a good peforming system requires multiple cards carrying the load of different aspects of the simulator display...for example, screnery controlled by at least one card and instruments by another. If you intend using multiple screens, "matrox triple header to go" appears to be the right direction. Attempting to run the entire simulator display (ie scenery gauges etc) off a single Radeon 6970 card in eyefinity mode will not produce the framerates needed.
hope this is helpful to someone
btw...what is that stupid box that keeps coming up over words highlighted in blue all about??? can we get rid of that off this forum its driving me nuts
