But I would not get the GTX 550 Ti. I run two of them and they cost to much for what they will do. A better step would be the 560 non ti or if you like AMD cards then I would go with 6870.

You should also make sure you have the right PSU at least a 400w for the 550 ti. I just wish I new about the 550 ti I surely wouldn't have bought them. It would have been the 560 ti one.

Anyway here is a bench mark to show you the difference. I do wish you Good luck on your build. I hope this helps.
