Overclocking GPU/CPU in order to improve the minimum frames per second - Some basic questions

post #1 of 4
Thread Starter 
1) I was wondering whether increasing core/memory on the GPU increases both your minimum and maximum frames per second or just the second.

2) Also I am wondering if it's worth overclocking the memory since I have heard that it provides minimum improvement compared to the core, for example raising my memory from 2000 to 2100 only raised my 3DMark11 score from 7006 to 7019, while raising the core from 845 to 900 raised the score from 6674 to 7006.

3) Also a CPU related question, does my current CPU (i5 2500K 4.5GHz) bottleneck my GTX 570 at high resolutions (1920x1200) and will I see an increase in minimum frames per second if I further overclock my CPU, to 4.7 for example, or it won't make any actual difference?

1 - Yes
2- Memory really doesn't effect that much.
2- No it doesn't bottleneck. And overclocking further would show a minimal boost.

1. Yes and no
The performance of graphics cards –be it in multi monitor, stereo 3D or single monitor setups- all comes down to a delicate balancing act. If the core can’t process information fast enough, doubling a card’s memory allotment won’t improve performance. Meanwhile, if bandwidth isn’t sufficient for the GPU’s output, a faster graphics engine will have no effect.

2. Games and applications like Civilization 5, League of Legends, Crysis or Metro 2033 are fairly different than the more synthetic benchmarks like 3DMark. This is doubly true given the extent to which vendors are known to use their drivers to optimize (or sometimes outright cheat) on benchmarks like 3DMark. In many cases, drivers are much more heavily optimized for big name games and benchmarks, while neglecting smaller titles.

3. Doesnt bottleneck it
