Radeon 5850 HD Intel ® Core ™ i7 CPU

That's just SPAM (you surely know doggoned well that it will). A month ago you started asking about a Radeon 9800 for Oblivion, claiming that you had already gotten one, and you asked it in three different threads. Then you asked about a very old and worthless MX 400 of some kind, so it's past time for you to make up your mind what you want, and to actually BUY whatever product you choose, rather than just play at shopping for PC parts.

My, what a machine you have thar. :blush2:

is that a yes?

That's a big YES. It's more than enough to run Fallout New Vegas on the Highest settings possible. If your rig was self-aware it would LOL in your face for asking that question.
