Your CPU will handle 1920x1080 just fine. I have a old P-35 with and E8400 dual core that works great at 1920x1080. Your PSU and your connectors are fine for any card using 6 (not 8) pin PCIe connectors. Your only limitation is your budget. Take the other people's advice and get the HD 7770. Too bad you can't afford an 7850. That card would play almost anything at 1920x1080 at good frame rates.
