Help me prove some kid wrong.. - Page 6

post #51 of 60
thank you!!

there is always a 'bottleneck' or limit in a computer or the game would run at infinite FPS all the time. most of the time the limit is the GPU in today's graphic intensive games. the only time a CPU bottleneck is an issue is if its limiting the GPU(s) so badly that you arent getting playable frame rates.

tribritar says he's testing but i just think hes over compensating for something. lol back on topic like many has said already that setup should not have a bottleneck

It seems as though three of us get it, and the rest just regurgitate stuff.

Although I do have to disagree with your last comment.

A bottleneck, in multi-GPU terms, is when adding a second (or third) card did nothing (or close to it) to increase performance --when it should have.

if it doesnt add performance, then the CPU is the limit. its not giving information to the GPUs fast enough and then there isnt a load on the 3rd card.

but youre still getting playable FPS with 2 cards. 3 cards never scales well. with more advancements in multithreaded games, the CPU will be used more efficiently and will be able to feed the GPUs faster

my statement was in layman's terms. if you are getting strong framerates, a 3rd card is usually not going to improve anything to a noticeable amount. that money was probably better spent upgrading the 2 cards you already have.

YES and NO.

at <1200P probably YES
at >1200P probably NO

this is all you need to know.....its Mostly dependent on monitor resolution the CPU speed & what not usually come into play after that.

Higher resolutions stress the GPU's more, which is why it's so easy to have very playable framerates at lower resolutions, due to the alarming number of overclocking around here Pushing more pixels will have less of an impact on CPU's.

There will ALWAYS be a bottleneck somewhere, but the impact isn't noticeable unless you obsess over benchmarks.

These channels probably did the smooth trick...
..my board has x8 electrical x16 slot..

bottleneck yes enough to make a difference no

price of 990x ??

price of 1100t??

is the gain worth the price premium
