GPU for older rig
My primary use for this PC is processing RAW files in Lightroom. Little bit of Battlefield series games when I have the time.
Other components include a 8Gb DDR2, Q6600, Gigiabyte GA-P35 something, and a 750W PSU. Running 2 1080p eIPS monitors. CPU/Mobo upgrade this coming year, when funds allow.
Budget is $150-$200.
What do you technically inclined slickdealers recommend?
