I'm thinking of adding a second 24" LED cinema display. I could really use the added real-estate, but I want to do so for the least investment. I originally purchased my MP with the BTO 4870 with plans to game in Windows, but just haven't been motivated... this GPU is currently wasted on me. So, I'm thinking of selling/trading the 4870 for a pair of GT120's... my only concern is I don't want to hack myself off at the knees when it comes to OpenCL performance... when apps start getting around to supporting that. Does anyone here know how dual GT120's compare in OpenCL to a 4870? What do you think of my plan? Good, bad or ugly?
