lots of great advice here, so i'm not going to add anymore. all i can say is theres rumors of some decent performance upgrades coming down the pipes for Haswell E so it might be an upgrade to wait for. some changes to memory and sata that ups the bandwidth quite a bit. Also as a boxer the more VRAM you have the better. i would wait for a 780 series with 6 gigs. Titans are overrated and avoid them. just my 2 pence worth.
