I5-2300 Bottleneck? gtx980

Solution
Hey max,

Your CPU only supports 16 PCIe lanes, so, if you ran the GTX 980 on the x16 slot, and added any other PCIe add-in card (sound, RAID, USB, storage etc), it will force card into a slower speed.

Also, if you decided to buy a second GTX and run them in SLI, they would each run at x8 (x8x8) -as opposed to x16x16 on newer mobos/CPUs

This can be a bottleneck..BUT -as long as you are just running that card and nothing else in any of the other PCIe slots- the card will function at 100% performance -assuming its not a dud card!

Hope this helps!

Yes! With one card in the full size/full x16 speed slot, (usually 99% of time the first slot)..all is well!

Happy gaming!
 
so, what about you talk here?

" It's not the 16 lanes that's the issue. The i7 4790k has only 16 lanes (and all i5s and most other i7s except the top end platforms)

8 lanes at pci-e 2.0 is plenty "

 


Was replying to NerdIT, where he implys 16 lanes isnt a lot , and 8 lanes can be a bottleneck.
