I am trying to decide between upgrading my current rig, the one in my sig, or building a new i7 system. I'm leaning towards just upgrading my current rig, since, for gaming at least, the i7's don't give that big of a performance increase. I was thinking of upping my RAM to 8GB and slapping a GTX 480 or a 5870 in there. Perhaps an SSD boot drive and a new monitor. Just wanted to get some input.
