Depends on your power supply. You might not need to replace it since today's video cards don't draw very much juice, but, then again, you might. Post what you've got. Replacing it with an adequate model shouldn't run any more than $40. The video card should be your first priority, as it will provide the biggest performance boost.
EDIT: As far as the CPU is concerned, apparently you're sitting on a Phenom II X4 already. PII X2s are simply X4s with 2 cores disabled. All you have to do is unlock the cores in the BIOS and stress test it. Of course, it's not 100% guaranteed to work, but, if it does, there will be no need to buy a new one, so it's definitely worth a try.
"They should rename the team to the Washington Government Sucks. Put Obama on the helmet. Line the entire walls of the stadium with the actual text of the ACA.
Fix their home team score on the board to the debt clock, they can win every game 17,000,000,000,000 to 24. Losing team gets taxed by the IRS 100%, then droned."
