I felt the same way lol, had a Dell Dimension 3000 which ran games at 5fps, then got a gaming build with the E8500 and GTX 260/550 Ti (replacement). All games were playing fine until Far Cry 3 and AC3 (my goodness less than 20fps). The near future won't really wreck your build to be honest, and given how newer games still look great at medium-high settings, it won't be all that bad
