For some reason my GTA IV has been "stuttering" even on low settings, average FPS 16

PC specs:

AMD Phenom II x6 2.9 GHz

8 GB RAM

1 TB HDD

ATI HD Radeon 5450 1 GB

That's because your graphics card is terrible and your processors clock speed is a little slow. A 6-core CPU won't help if the six cores aren't being used. So clock speed matters for modern games. Graphics card is the major perpetrator here though. Gut that thing and replace it with something more substantial, and a new power supply to run it.

What kind of graphics card would you recommend for a 550w psu?

Lol that's weird i have a x4 2.8 and a 9800 GTX i think or GT and run it smoothly on high.

Running on Laptop:

AMD Athlon II X2 P340

AMD Radeon HD 6650M

4 GB DDR3 Memory

750 GB HDD

And mine runs fine with a command.txt, Get it here.

That, I'm using that and it works fine, maybe you want to add -windowed to the line if you want it windowed, it works sometimes, I had it at first, but then I deleted it, and it ran fine.

So try that, it helped me, works like a charm.

What must i do to get this on work ?

Commandline.txt?

1. Download it.

2. Put it in the Main GTA IV Folder.

3. See if it works.

4. If it work, have a glass of cola and enjoy your IV.

A 9800 is a stronger card despite its age, and you probably run it at a reasonably low resolution. Either that or you don't have everything maxed out.

To the original poster: For a new video card, I'd try an AMD Radeon 6950. Reasonable degree of performance, and it's actually the same board as a 6970. You can even re-flash to BIOS to make it a 6970. Pretty cool stuff.
