Well GPU will always get hot wen running at full power. If heat is the only reason you are considering an upgrade then just clean the dust out of it and perhaps change the thermal paste. GPU's don't get hotter over time its the cooling that starts to loos efficiency. With a clean cooler and fresh paste the temps should be the same as the day you bought the card.

+1 On that idea. Also to answer your question OP though I run a 965 at 3.6 Ghz with stock voltage and it doesn't bottleneck my 7870 at all. So you can upgrade if you want but I wouldn't yet, just listen to this guy, clean your GPU and start overclocking.

Off topic but I would seriously recommend overclocking the NB if you haven't done so yet. It increased performance on Phenom II's more than there clock speed. Mine is currently walled at 2600 Mhz, I think I can do 2800 Mhz with 1.375V but I don't think it's worth pumping that much voltage into it.

Your question is pretty meaningless. In response to a similar query:

Basically: in SC2, you will be MASSIVELY CPU" bottlenecked". But this would also be true with an overclocked i5-3570k.
For, say, BF3 singleplayer, you will likely be "bottlenecked" by the GPU, not CPU, though whether you are "bottlenecked" at all depends on your monitor's resolution.

Relevant post I made on the subject:
Warning: Spoiler! (Click to show)
There's a difference between different definitions of bottlenecking. If you mean the correct (according to me) definition, then no.
Correct definition: A bottleneck is a result of one piece of hardware not permitting another to function at its full capacity in any circumstance.

Correct definition example: You have a SATA3 SSD plugged into a SATA2 port on your motherboard. The SATA2 port is bottlenecking your SSD - you can never get faster than SATA2 speeds out of it, even though the SSD could perform much better.

Solution: Plug the SSD into a SATA3 port, possibly requiring a motherboard upgrade.

HOWEVER, lots of people use a different definition of bottlenecking. According to me, the incorrect one.
Incorrect definition: A bottleneck is when one piece of hardware is not performing up to its maximum potential in a specific task because another piece of hardware can't keep up.

Incorrect definition example: You have a 5850, which is capable (or nearly so) of displaying SC2 at maximum graphics settings at your monitor's resolution & maximum refresh rate (best possible image quality at maximum effective FPS), however, because your CPU (i5-2320) cannot run SC2 at maximum FPS (your monitor's refresh rate) when large armies are on the field, you aren't getting maximum theoretical potential out of your 5850.


The difference is that the second (incorrect) definition is task-specific. Sure in SC2, there's a CPU "bottleneck," but for the vast majority of games it's the opposite: your i5-2320 is more than enough power to do everything you want other games to do, but your 5850 will hold you back.

So to answer your question:
Your system has no bottlenecks (first, correct definition).
Your question is meaningless without giving us context in terms of what software you're running (second, more common but incorrect definition).

The reason the term bottlenecking bugs me so much is that people hear they have a bottleneck (incorrect definition) and assume they have a bottleneck (correct definition) and that there are magic hardware configurations that will never have bottlenecks (incorrect definition) when that outcome is, in fact, impossible.

The GPU, I thought you wanted to upgrade so you could get better performance as well as a cooler running card. If your happy with it's current performance then by all means don't overclock it.

If you dont plan to upgrade your monitor soon then grab a 7870. Even a 7870 is faster than you need for this resolution. If you plan to upgrade your monitor soon then grab the 7950

But honestly why would you upgrade anytime soon? Your current 6950 1gb isnt that far off the performance of a 7870.
