Do you think CPU Bottleneck?

Alright, so my friend has talked me into upgrading my video card, and I agree.. I am due for an upgrade.. (probably a new build, but that will come later).. Anyways, my current system has an Athlon II X4 640 running at 3.0GHz. I am currently running a HD 6770, getting kinda bad FPS.

I would like to update AMD R9 290. My friend said I won't have an issue, and it wouldn't hold me back as much as I think.. But I keep telling him that it would bottleneck like crazy.

So.. I'm looking to be playing Watch Dogs, GTA 4, Battlefield 4 and all that such.. Will it bottleneck and jitter or will it be fine to play it at decent FPS.

NOTE: Board is running DDR2 866MHz.. Again, he doesn't see an issue with that either.

It would bottleneck. The Athlon 640 is weaker than my CPU, and my CPU bottlenecks my GTX 660 in some games.
I'm sure it'd still improve your performance substantially, but you wouldn't be able to use the full power of the 290X in many/any games. There'd be no noticeable difference from a 290X to a 280X on your current CPU and RAM.

I'm going to be upgrading in the near future, for sure. (Board, RAM, CPU) Not going to be sticking with this Athlon garbage, since I do see some struggling with most things. Just temporary for now.

Gaming laptop GPU fried itself after a month of purchasing it from ebay. Never again for laptops. It now sits as a very heavy web browsing machine.

If you're going to upgrade then get the 290 and overclock the cpu.

The cpu will bottleneck the gpu in most cpu intensive (and not so intensive) scenarios, but according to how good / bad your experience is you'll be able to more wisely choose an appropriate platform and cpu to upgrade to.
