bottleneck please help

avatar195 · Jul 23, 2014

when im gaming my graphics card (quadro 570,i know its a work station card im getting an upgrade)it bottle necks with my cpu (e8400 3 ghz).
while my gpu is working 100% my cpu is working at like 50-60 % please help

Danbuscus25 · Jul 23, 2014

well, it means that you need a stronger gpu, because your current one is bottlenecking your cpu.

Danbuscus25 :

cheers thanks i am upgrading to a 4850

Danbuscus25 · Jul 23, 2014

why dont you get a newer graphics card? that one is 4 generations old. what is your budget for a new graphics card, and what psu do you have?

Danbuscus25 :

i only have pcie rev 2 so im limited to what i can buy and i am upgrading my current psu to a seasonic g series 550w

Danbuscus25 · Jul 23, 2014

you can put any gen pcie card in any gen pcie slot.

LucoTF · Jul 23, 2014

Danbuscus25 :

Very nearly this. A very small number of pcie 2.1 cards have problems with pcie 1.0 but otherwise yes, any card for any slot

Pcie 2 will take anything no problems

Danbuscus25 :

really ? will it only run at the speed that the pcie lane runs at ?

avatar195 · Jul 23, 2014

i am as well upgrading my ram from 4 to 8 gb

LucoTF · Jul 23, 2014

Why, do you have an x4 lane or something?

no i have a 16 x
elecrical that is

Danbuscus25 · Jul 23, 2014

for a low end card, the bandwidth limitation of a gen 2 pcie lane will have no affect on the performance of the card.

LucoTF · Jul 23, 2014

avatar195 :

The you have no worries, pcie 2.0 at x16 speeds is more than enough bandwidth for any card.

Hell, even if it was x4 a card would still run at 90-95% speed of the same card in a bigger lane.

no problem, and dont forget to pick the best solution to mark this thread as solved

Unless your current PSU is total garbage you could save some money here.

Just buy a GTX 750 - your CPU will bottleneck it a little but you will be able to turn the graphics up quite nicely on a lot of games and it's very low power so you probably won't need to upgrade your PSU.

my psu is 375w its dell stock one

LucoTF · Jul 24, 2014

That is a good PSU, more than enough for a GTX 750

LucoTF :

really ? : /
what about a 6850 i recently purchased thats card will it work?

LucoTF · Jul 25, 2014

avatar195 :

The gtx 750 has a tdp of 55 watts

The HD6850 has a tdp of 127 watts

That's pushing it but it could still be enough, depending on what amperage the dell PSU has on the +12v rail (it would be on the sticker on the side of the PSU, my guess is it's around 19a).

Also, I believe the 375w dell doesn't have a 6 pin connector for the graphics card? If it doesn't then I would buy a new PSU before installing a 6850

no i does have a 6 pin
and it does have a 12v rail
if i was to buy a new power supply it would have to be 13cm long

LucoTF · Jul 25, 2014

What is the rating on the sticker for the +12v?

avatar195 · Jul 25, 2014
