I am looking at the three eVGA cards. The one on the top left has faster speeds so, but the other two don't appear to have any difference? Also, is the top left one the CO edition? What's special about the CO edition? Thanks.
While I'm at it, how's my potential system look?
Athlon 64 3200+ Venice
XP90 w/ Zalman 92mm adjustable fan
DFI Lanparty UT nf4 Ultra-d
Corsair Valueselect 2x1GB
Samsung Spinpoint P Series 160GB Sata3.0GB/s
Cooler Master Centurion 5
FSP Group (Fortron Source) 450W
I was looking around and I found another version, this one without COD2, that confirms it has the copper heatsink. Should i go with this one since I don't care about getting COD2?
