I don't post much, but I am here everyday. Anyways I was looking for some advice on my GPUs. I have a XFX 6950 with unlocked shaders/stable and I recently bought an ASIS XFX 6970 on Ebay, RMA'd, and they sent me a new 6970 in the retail box!...... Should I keep the 6970 and crossfire, or sell em both and get a 7970 ?.... Thanks for looking.
