There's really no such thing as 'having a CPU bottleneck' in any absolute sense of the word.

You see, every single frame ever rendered by your machine is a new chance for either the cpu or the gpu to be the 'limiting factor' to performance. It all depends on the game (i.e. how much work does that particular game require of the CPU per frame rendered ... which varies constantly depending on what's going on) and the settings you run it at (mainly important because higher settings = lower fps, which means less work for the CPU per time-slice).

Ergo, OF COURSE you should OC your GPU thumb.gif As long as you're not abusing it with excessive heat and voltage, there's no downside whatsoever. You WILL get higher FPS, a LOT of the time.

Some games or benches, you maybe won't see a big improvement at all times, esp. highly CPU-dependent (or quad-enabled) ones like GTAIV, Skyrim or BFBC2, but for the lions share of stuff out there, and most of the time, you will.

It's all about 'frequency' and 'severity' when it comes to bottlenecks ... it's not a binary (yes/no) situation based on hardware alone. The more extreme the disparity in power between cpu and gpu, the more often you'll have a BN going on. Your single 560ti is not SOOOO much more powerful than an e8400 that it's going to make OC'ing the card useless.

If you had SLI 580's, I'd maybe say 'meh ... don't bother unless you're rocking 3 monitors (hence very high gfx settings)'. But with your gear? Hellz to the yeah thumb.gif

One more question and then im going to push this thread to rest.. So my board is several years old, its been a very good board and a dear friend of sorts. I will upgrade but its just an issue of putting the money together.

Question: With this board only supporting PCI-e(version 1), would dual gtx 560ti be something to consider for a moderate to very notice increase in preformance/quality?... I'd like to hold off until IB comes out, but i'd still like to continue to max this board as much as possible.
