i found out that running 2 dedicated cards makes both cards run and the lower cards memory in my case 1gb and i thought that the memory added up so having a 1gb card and a 2gb card ment i gave 3gb but what i have learnt is that the lower card brought both cards down to 1gb memory then i found out that the memory doesnt add up its actually mirrored memmory which means them memory on both cards is seeing the exact same thing so where my lag problem came in was that my now 1gb or graphics memory was getting filled up very very fast and dumping into my ram on my computer thus filling up 6gb of ram and causing my system to lag very bad. once i took my 1gb card out i can now run battlefiely on high settings with no problem at all running one 2gb radeon HD7770
