ok so i think im having cpu bottlenecks , i'm getting 50% gpu usage in more CPU intensiveness games such as Battlefield 3 MP 64player , my HD 7970 Crossfire are all over the place on usage, this is with max settings , from like 50% when action ramps up to like 80% 90% depend's whats going on, now i could Overclock more, but honestly i don't think i'm going see as much of significant usage on my GPU's so i'm thinking my only upgrade path is ivy bridge and i was wondering get i5 version or i7? i was told HT should remove my bottleneck if i OC to 4.3 4.4ghz il buy a corsair h100i for it. any advice on trying remove this bottleneck :/ im really stumped on just OC what i have or try my luck of on ivy
