Hi,
A few weeks ago (beginning of the month to be precise - Alaska PFD yay!) I purchased a Radeon HD7870.
Prior to purchase I did some light research and I was under the impression that by installing this card into a PCIe 2.0 slot I wouldn't be losing too much.
This is the card: http://www.newegg.com/Product/Produc...82E16814150605
This the board: http://www.newegg.com/Product/Produc...82E16813157163
This is what was replaced: http://www.newegg.com/Product/Produc...82E16814102856
Unfortunately, the performance I'm getting isn't much better than the HD5870. Thus, I have a few questions.
1. What am I losing in the PCIe 3.0 to 2.0 downscale?
2. Is this the primary cause of my not-very-much-improved performance?
3. Somewhat/maybe unrelated: the Catalyst Control Center for this card seems completely the same. I was under the impression that the CCC exposed different/newer options for these cards. If so, what's causing me to not see them?
4. Several games still show my graphics adapter as the Radeon HD5800 Series. When I installed this card, I did a clean driver sweep. Uninstalled the drivers, used Driver Fusion in safe mode(driver sweeper's replacement), rebooted, installed new drivers, rebooted. CCC says 7800 Series though, so I have absolutely no idea what's going on here.
5. Longshot: Sometimes when I move my mouse over a link in Firefox, the entire screen goes creamsicle orange and I have to do a hard reboot. This is the only instability I've encountered. Anybody else come across this? It's only in that very specific usage. Movies, music, games, whatever. Just fine. Hover over a link though and bam.
So yeah.
