The to Nvidia cards only works at PCI x1 1.1, so it is bandwidth starved, but all the games I tested, new and old were playable 35+ frames. I tried Borderlands Pre-Squel, Crysis 2, Just Cause 2, and FEAR 2. I was able to max out all settings for all the games and typically got between 35 to 60 fps at 1600x1200. The performance between the 570 and 760 were close. The 570 was a little slower, and more power hungry, as it would break 200 watts under Furmark (measured with a Kill-a-Watt on the DA-2 plug).
Though using an external screen the frame rate was higher than internal laptop screen frame rate. It seems that using internal screen starves the GPU of bandwidth.
Benchmark wise, the scores were decent, but you could see how bandwidth starved these cards are. Benchmarks that saturate the bandwidth but not the GPU have a wide range of variance fps, ones that fully load the GPU but not the bandwidth get scores very close to the cards true performance. Standard 3dMark Fire Strike score was 4900 (should be 5600), and extreme 2650 (should be 2700), from the 760 on the external screen. On the internal screen the standard score was 3600, while the extreme score did not drop much.
I hope to to try to get the PCI-E working at 2.0 and 2X, as the chipset support it. Any suggestions?
Hope this was helpful

Das sind synthetische Tests!

1. Einfach nur mal wissen willst wie viele dieser tollen Gummipunkte deine Karte bekommt.
2. Deine Karte voll auslasten willst um deren Hitzeentwicklung zu ermitteln.
3. Deine Karte voll auslasten willst für maximale Temperatur um deine gewählte Kühlung auf Effektivität zu überprüfen.
4. Beim übertakten der Karte schauen willst, ob der von dir zuletzt durchgeführte Schritt überhaupt Leistung erzielt oder eben nicht. (mehr Gummipunkte als vorher oder weniger)

Based on id's idTech5 engine, another noteworthy title with large drops in performance is Wolfenstein: The New Order. Virtual Textures certainly look great in-game, providing highly detailed, non-repeating textures, but they also put a significant load on the PCI-Express bus. One key challenge here is to have texture data ready for display in-time. Sometimes too late, it manifests as the dreaded texture pop-in some users have been reporting.
