AMD Radeon HD 6970 vs 4890
Currently I have a Radeon HD 4890 1 GB. I'm looking to upgrade soon, and was looking at this:
Newegg.com - PowerColor AX6970 2GBD5-M2DH Radeon HD 6970 2GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card with Eyefinity
How much of a performance gain could I expect from switching my 4890 for that?
