Do yourself a favor and invest in a 5Dmkii or mkiii. The ISO performance alone will be substantially better than the 5D. Your lenses are fine. Also consider that the newer the camera, the higher the resale value if you need to sell it to upgrade. Also, if it needs repairs, the older the camera, the more likely it will be that you may encounter issues.

not to mention the 5dc just feels old now and the screen on the back is depressing....etc. doesn't affect iq but it does affect the experience.
The ISO performance of the 5D is no worse than the 5D2, or 5D3 for that matter. Of course, the 5D only goes to 3200. If you are comparing JPG shots from ANY bodies, you are comparing JPG engines, not the sensors capabilities. There have been some interesting threads recently showing that the IQ differences between the 5D, 5D2, 5D3 and 6D are almost non-existent if you shoot raw, which compares the sensors, not the Post-Processing algorithm built into the camera.
The higher ISO performance of my 5D easily outclasses my 60D, which is nominally better than the 7D. The 5D's AF system is identical to the 5D2. I used my 5D last night for the first time in a real-life snap-shot situation. It was a dimly lit Christmas dinner situation. My camera metered 1/4 to 1/15s at f/5.6 and ISO 3200. Not much light at all. I used center point only and go no AF misses I could blame on the camera.
I agree about the 5D feeling old. The menu system is archaic if you have used something newer. The rear screen is also good for framing and histogram checks. Do not rely on it for anything else. I think the worst thing about the 5D is that it has no sensor cleaning system. If you go that way, buy a Rocket Blower, you'll need it.
I think the 5D would satisfy the OP needs with the least amount of financial pain. Put the extra money into some glass/accessories.
