This won't last you 5 years. Come back with a total of $800 and I can get you something that MIGHT squeak by for 4. $400-$600 will get you around 2-3 (being very liberal). You'll probably see that 560 go to the slow side within 1.5, and the CPU will be ashes (it's already old as dirt) in about 2 years. Save another $200, or expect things to be dead slow compared to everything in 2 years.
But doesnt Software Move as Fast as the hardware that supports it? Im aware of Mores Law but As it is, Only a handful of games are truly multi-threaded and support Quad Core, While some still support dual (atleast afaik).
2 years of use is fine by me, but I just wonder how I got 5 or so years out of a socket A rig, shouldnt a quad last the same? However doesnt longevity depend on Usage, frequency of gaming, and keeping tabs on todays games? I have to wonder if social networking will play a great deal in Future Upgrades, since back in 2002ish, there was none of that (or very little)
