Well, the G1 fun was short lived 
Ive removed the old AMD drivers. Got the latest Nvidia ones from Nvidia and ran some benckmarks on 3DMark (let me know if you wanna see them).
Now I loaded up CSGO to see how many FPS ill get hoping it would blow away the 200-280 range i was getting before on the same settings. To my surprise Im hitting 180 max while playing. I've got Afterburner open and i can see the clock is sat at 1850~. I check all the settings and i cant find anything that would affect it. I uninstall all drivers except graphics and sound.and re run it and its still the same.
When i stand still however I'm hitting 500 steady which is the cap i have.
I feel like I'm missing something basic and could do with someone making me look stupid... any ideas?
Specs are on my sig.
