Two GTX 550 ti's would be better because theoretically, it will double the performance of one gtx 550 ti. So 2 GTX 550 ti's will be a better choice. (If you have a good PSU)

It's hard to know what applications the OP meant by better. VRAM doesn't stack in SLI. Some applications may require higher VRAM. I'd still pick the latter.
