I have a 24" (1920x1080) LCD. I'm moving up to SB (using a board that supports both SB and IB). Should I go with the Sapphire 2Gb 6950 (newest one has the label 3L at the end) or MSI Twin Frozr III which I saw is highly recommened; although both are. Would it be a waist to get a 6970? I was going to get a 6950 until the 7870 comes out (or if the 7970 is lower than the $550 that it's rumored to be).
