mine runs crisis at 12fps 800x600 woo!.. 361 3Dmk 06 score too..

as for the original posters question of 'is it worth it'? if you could post your current pc, we could probably make a better argument to try and tell you whether its worth it or not, because with the spec you've chosen in about 1 or at a push 2 years, you'll probably need/want to upgrade again.

If you have little money (like me) then i would say suffer for a while longer save up more money and get a better system that will last longer. besides its fun seeing which current games mine can run, whilst everyone else is frantically upgrading just because they don't want to fall behind their mates pcs.(or whatever drives people to upgrade in the first place). i quietly laugh at them, because mine runs almost everything (except COD4 and clive barkers jericho).

If your current pc runs everything you want to, then why upgrade?

am i ranting? i will stop now.
