Will my rig bottleneck the RX 480?

[Eballtr]

I'm looking in to upgrading from my GTX 750Ti to an RX 480 4Gb. Would my Phenom II X4 940 overclocked to 3.6Ghz and my 8Gb of DDR2 RAM bottleneck the new card?

yes, i would think you'll experience a little bottlenecking. In CPU dependant games it will be held back. Perhaps it won't be that bad if your oC'ing to 3.6. That will help a lot. There will be other games (more GPU dependant) where it won't impact too badly.

I second this almost to a tee. If you can get a good enough overclock the bottleneck will be minimized, but it will still be quite noticeable in those more CPU dependent games where you want to push higher frame rates at high settings.
The DDR2 memory will most definitely bottleneck however.
I think you should upgrade to an i5 6500 along with DDR4 RAM and a new motherboard, as you're long overdue for an upgrade.
This is essentially what you want, it will last you a good 4 years before it becomes outdated, but even then it will still keep up with the latest titles.
