GTX580 bottleneck

[axehammer]

Hey all,
I just ordered a gtx580 for my rig at work. it has a 1045t and 8gb of ram. my question is how bad will my cpu bottleneck my gpu without an oc?
also it has the hp motherboard so no overclocking obviously. could someone recommend an affordable mb to swap out for some mild oc on the cpu?

what is your budget? The 1045t has a turbo mode @ 3.2 as well, so they kind of OC themselves for you to a certain extent.

budget of $200 i guess. the local shop i called is recommending some new gigabyte board that he is not sure he can even get yet
do you think the 1045t stock will be ok for bf3? from what i understand it is a beast hardware wise.

you will see some bottleneck with the 1045 but your mobo im assuming since its HP is stock with the 6 core? should have the turbo frequency, and be ok to play BF3 if you dont want to be upgrading. you will get better performance out of a good OC, esp with that 580 being held back a bit, but you should be able to play nonetheless

this is what im running, it has am3+ so bulldozer ready, and overclocks very nicely. bios were a snap. it would be a good option for you if you were going that route to get a new mobo

I believe that frostbite 2 (bf3 engine) can make good use of 6 cores. If that is the case then you may not even be bottlenecked by the cpu.

i want to squeeze as much as possible from my 1045t without water cooling. yes it is stock with the 6 core. i would like to upgrade but nothing major, as i have a rig at home that will need some work. it has 955*be (unlocked two cores) and a 470

 

[axehammer]

@lozz08 i was hoping they would optimize it for six cores, you really think no bottleneck? that would be great.

how would i find out if i have a bottleneck?

 

[FlintIronStagg]

i think you will be ok to play bf3, with the option of changing the mobo out in the future when you want to OC your cpu and get more performance out of your setup

 

[axehammer]

thank you flint for all your timely replies. i do want mobo for sure, the link you put brought up blank page, could you tell me what it is for me to look up? thanks

alot of times the easiest way is to change your resolution down and see if your performance is near the same as 1920x1080. Or OC your CPU and see if there is a performance increase.

that mobo looks good for the price flint, thank you. its 100 cheaper than the one the local shop is pushing too.

not a prob, im using it, and love it. it also has an automatic overclocking thingy i dont use called OC genie if you want to make it easy for you

 

[axehammer]

i probably should use that (about broke home pc trying to overclock) as im no expert but do enjoy tinkering with it. also that mobo would support two 580?

 

[FlintIronStagg]

that mobo says pciex16 on both ports, but ive seen people not getting the best performance out of the 2nd slot saying its a x4 when doing xfire, and do not think its sli certified. If you were wanting to SLi, then you will need to spend a little more money and get a better mobo with 2 pciex16 slots or even one with a x16 and the other x8 at the least

 

[axehammer]

im not looking to sli, its more of an afterthought really cant imagine needing two 580s

 

[FlintIronStagg]

you most likely wont. i enjoy having problem free single card setups. there are people that have problem free dual card setups, but other horror stories make me skeptical.
