The Powercolor 6870X2 is a 900MHz Core Clocked Dual GPU design like the ASUS MARS cards. The Powercolor Devil 13 6970 is a stock 880MHz Core Clocked 6970 with a Turbo Functioning Core Clock of 960MHz.
Powercolor 6870X2:
Core Clock: 900MHz
Effective Memory Clock: 1050MHz (4.2Gbps)
Video Memory: 2GB
Memory Interface: 2 X 256bit (256bit)
Memory Type: GDDR5
Powercolor Devil 13 6970:
Core Clock: 880MHz/960MHz Turbo Mode
Effective Memory Clock: 1375MHz (5.5Gbps) / 1425MHz (5.7Gbps) Turbo Mode
Video Memory: 2GB
Memory Interface: 256bit
Memory Type: GDDR5
1.A. The 6870X2 can OC to 965Mhz @stock voltage. WITHOUT an OC, will the DUAL 900Mhz Core Clocks of the 6870X2 outdo the SINGLE 960Mhz Turbo Function Core Clock of the Devil 13 6970?
1.B. And likewise with the two cards' Effective Memory Clocks? Will the DUAL 1050MHz (4.2Gbps) Effective Memory Clocks of the 6870X2 outdo the SINGLE 1425MHz (5.7Gbps) Effective Memory Clock of the Devil 13 6970?
2. Can the Devil 13 6970's Turbo Function OC pass 960Mhz? I ask this because I do not consider Turbo Mode an OC, but an energy saver.
Other details:
Resolution I will be playing at is 1920X1080p 60Hz. Mostly Crysis 2 DX11 on Ultra, Crysis DX10 on Very high, and I wish I could play BF3 on Ultra but I've heard that Ultra requires at least 2 GTX 580's in SLI.
PC Specs:
CPU: AMD Phenom II X6 1055T @2.8GHz
