I just did a new system, or half of one.  And honestly I don't notice a difference in the games I play.  Only reason I bought a new one is I spent 6 month's trying to figure out why my old one was crashing while gaming and couldn't figure it out.  With lock down on the horizon the last thing I wanted was to have no gaming machine.  I went ballz deep on the hardware because I'm going to sell my server's and replace both of them and my gaming machine with just one machine, same thing a friend of mine did.
