Hello all! I currently have an ASRock A780GXE/128M, 8 Gb of G.Skill DDR2 800 (5-5-5-15), AMD Phenom II X2 550 BE (at 3.6 GHz), two PowerColor PCS HD4850 1 Gb (4850 XFire). The OS is Windows 7 64-bit. I'm itching to upgrade either the CPU or the gfx cards. For the CPU I'm looking at the Phenom II X4 955 BE and for the gfx card I'm looking at a single HD 6870. I figure when AM3+ MBs come out I'll get a new board, switch to DDR3 and get a 2nd 6870. But for the time being, what should I upgrade first, the CPU of the gfx card? Thanks!
