iMac 27" mid 2011

[gfcllc]

I have two iMac 27", mid-2010 and late 2011.
I don't do any gaming, no CPU intensive, just financial charts.
I would like to replace video cards with 2GB or more. I am handy, but don't want to do any soldering or transferring firmware from one chip to another.

help

The 2011 - Apple offered a radeon hd 6970m 2gb card. Just grab one off ebay.
