Futureproof?

Hello guys,

I have recently upgraded my rig to now include 12gb of RAM Corsair vengeance 1800mhz and a Sapphire 7970 GPU. The rest of my system is as follows, Gigabyte X58 UD3R revision 1 mobo coupled with an i7 930.

I just want peoples opinion please of how long can I expect this to play latest games a 1920 x 1080? I was told by some people on a previous post that my CPU at stock 2.8ghz would cause a bottleneck, I can assure that is not the case, and compared to the 6gb of ocz RAM and the 5870 I was using, it goes like stink! I was hoping to get maybe 3 or so more years out of this?! I am not expecting exact dates etc, just whatever your opinions would be if you were me?!

Thanks.
