Depending on the games you play, there are some specific hardware upgrades that will do well. For Arma, 8GB of data streams off the Hard Drive during gameplay, so many have installed another hard drive, like me, and installed the game there. Some have even used a OCZ SSD (hard drive) to install Arma too, like Savage's lucky arse. I would also add that the hard drives I use for my OS in RAID-0 are Seagate Barracuda's, and their beauty lies in their 16MB buffer and 7200RPM speed. IMO the best consumor priced hard drives for a RAID setup. (RAID-0 is striped array, half data on one drive, half on the other for a 2x read/write performance boost) Summary: A new GFX card is a great idea, and will show instant improvement, but also examine how the data gets to it. You have a great CPU for now, RAM is fine, but can you increase the stream of data beween the 3 key parts up to the limits of the Mother Board? Guess it depends on the games you play. After building an Arma system, I realize that it eats all other games for breakfast...Arma is THE system pusher to date. \
