A basic certified IFR GPS and a current data base and your have an IFR platform.

Ahh.. this explains why everybody seems to be putting GTN650s in their panel. I was wondering about that.

you can also go with a 625 (no VOR/ILS) or a 600 (no radio/VOR/ILS).
I elected to go with the 650 even though it was a decent bit more expensive. I like having the ability to track a VOR or shoot an ILS approach if necessary.

A few additional points to consider besides just price:
* A consistent user interface across boxes will reduce the probability of error. If you hope to fly IFR and are on a strict budget, maybe you should reconsider. And you will go nuts interfacing items from different vendors, even if it is theoretically possible;
* I worked in user interfaces and avionics a number of years before I retired. Pretty much all systems have problems, and even the best manufacturers don't like to make changes. (Our engineers love it, so what's wrong with you?). There are traditional steps to get up the user interface learning curve: ground training (very hard to find and limited); manuals (too often a check-off item and rarely answer all your questions); flight training (the FAA will let you get airframe training for hire in an experimental but not avionics training in an experimental); and experience. My friends at Garmin may cringe at this, but I'm just starting to feel comfortable after 100 hours, and there's still more to learn;
* The amount of functionality on glass systems is staggering, and then multiply that by the number of options and settings. I sometimes wonder if my conversion to glass was more work than my original instrument rating. (And I had lot of exposure to airline and bizjet glass).
If you're going to do IFR, do it right or don't do it. And one wise friend in pre-autopilot days said that his RV was great for IFR as long as he didn't have to do any paperwork, meaning clearance or chart. These days it's real easy to get distracted with the programming and not fly the plane.

I respectfully disagree. My panel has GRT, Garmin, Dynon, Trio, Trig, Skyradar, and home brew audio panel. It all works, and works together, just fine.
Or maybe I'm already nuts! -

For me, the different sequences of button pushes, different hard/soft key functions, different graphical user interfaces, etc. across various companies (and even within the same company sometimes) was a annoyance when installed in the same cockpit, or bouncing between cockpits. I had in my plane (among others) GRT and Garmin glass, plus glass in my work aircraft, and flew a couple other GA aircraft with various glass (G/avidyne), and iPad jepps and iPad foreflight. I found each mostly intuitive and easy to use on their own, I read the manuals and learned to use them well, etc., but would sometimes hit the wrong button(s), look for something that wasn't there, or expect a different outcome/interface from certain button pushes because my mind confuses similar but different interfaces. Entering airports/wpts in the G696 or G1000 was different than the using GRT or foreflight. No matter how much I "learned" it, after using a different piece of equipment to do a similar function, then going back, my brain always wanted to confuse the methods of input.
It wasn't anything more than a small annoyance, shifting my brain from one train of logic to another, akin to me bouncing between my Mac and Windows computers, or one FMS manufacturer to another. Once using it a few times, I get it down, mostly. But, I still hit the wrong buttons on my FMS at work (honeywell) due to the similar but different buttons/menus on my previous FMS (collins), and the law of primacy, etc. And I haven't used the old one in a year. I don't mind flying behind any particular glass manufacturer, but having consistency in interfaces is nice, especially within the same cockpit.
Throw in hardware/firmware/software compatibility issues, and that could cause an even bigger headache (at least initially). It sounds like, in your case, that isn't an issue. And I know several others who haven't had issues. But, I like seamless integration and common interfaces, personally. Perhaps if I consistently flew behind only one panel that used multiple (and varying) products, my mind wouldn't play those confusing tricks on me.

Bob, based on all your wonderful posts in the GRT help threads, I'd guess that you're already nuts!

Will try to reply to some of the questions.
The G3X is awesome.
It pairs well with many Garmin radios in panel or remote models.
Use Garmin servos and auto pilot and you will not have people pointing fingers at each other.
Use something like the GTN 650 to get wass/legal IFR
You then have a moving map on GTN, virtual vision on G3X and approach chart on other half of G3X with position superimposed on maps and chart.
You can have both Garmin ADS-B in and out tied into remote transponder etc, etc.
Even the new G5 serves as a back up that can work with autopilot servos when set up correctly.
Yes, I am a Garmin fan and love it.
