Are 3.0 Graphics Cards better to have than 2.0 Graphics Cards, if I have a PCI 2.0 slot?

I have this computer http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay?javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken&javax.portlet.prp_ba847bafb2a2d782fcbb0710b053ce01=wsrp-navigationalState%3DdocId%3Demr_na-c03500676-6%7CdocLocale%3D%7CcalledBy%3D&javax.portlet.tpst=ba847bafb2a2d782fcbb0710b053ce01&sp4ts.oid=5295962&ac.admitted=1387232651560.876444892.199480143


I upgraded to a power supply that has 600 watts; it was really cheap and really good. However, my motherboard only has pci 2.0 slots for graphics cards. I know that the pci 3.0 works on 2.0 slots, but their performance is also limited. I want to get a r9 270, but I want to know whether getting a pci 2.0 graphics card would be better or worse than getting a pci 3.0 graphics card.

Thank You
 
Solution
You wont lose almost any performance with a pci 3.0 GPU on a pci 2.0 x16 mobo. Only at pcie 1.0 x16 the performance would be a bit less but still good.
