best option for imac GPU replacement
so currently have a iMac (21.5-inch, Mid 2010) with a dead GPU was wondering what my options are for replacing it . found an ebay listing with this tittle "Apple iMac A1311 AIO GPU ATI Radeon HD 6750M 256MB - 2011" and was wondering if it were sufficient . If this doesnt work whats the lastest and greatest GPU i could use for this baby.
