I currently have i5- 2500k @ 330GHz - 360 GHz with H61M-D2H MoBo. It has 16 GB 4x4mb Ram slots and I use 8 GB 2x4 MB presently. I recently installed Asus GTX 750 Ti GFX card [NVidia] with 500 MW PSU. My old card Nvidia GT 610 [PC Express 2.0] has no takers. I am thinking can I use both cards together in a MoBo that supports such a thing and if so which MoBo would help me and how much PSU I would need? Will both cards combine to give me more FPS and faster gaming experience?
