Thanks Gent for all your help used the latest driver cleaner and some finger trouble on my behalf around vector. Forgot I had turned on all settings a couple of days before install . Kills a PC over dense areas newbie error just forgot with excitement of my new card . Frame rates not startling and carrendo stock over London ftx England high teens in cockpit low but smooth 4x antialiaing.Trying to up my overclock to 4.2ghz as high as I am comfortable with without watercooling . Good air cooling evo fan. Still testing if still not satisfied will RMA as EVGA have great returns policy and then re-format.
