Is my processor letting my graphics card down?

I was wondering if my i3-2120 @3.30ghz is letting my Sapphire Radeon HD 6870 down, the reason i ask is because i can only play crysis on all medium settings with a resolution of 1366x768 and even then its still jumpy at times. During gaming im only using around 40% cpu usage so i dont understand what is wrong, any help would be appreciated.

Windows 7 64bit
8GB ram
1TB hd
22 inch led screen
Sapphire radeon hd 6870 1gb gddr5 "not overclocked"
Intel i3-2120 @ 3.30ghz dual core.

What powersupply do you have? Your cpu is enough for a 6870

It could be that your powersupply isn't supply enough power to your graphics card .

Its a 600watt psu, could it be my motherboard thats doing it its a "Foxconn 2abf".
I was sure 600 watt would be enough for this card i only have 1 hdd and a dvd drive to power along with processor and ram and 4 fans.

Whats the brand name? just because its a 600 watt PSU doesn't mean its any good.

How old is this PSU? after time they don't work as well as they use too!

that CPU may not be the best, but gaming wise it's enough to drive even something like a 7850 or 7870 maybe with the exception of bf3 multiplayer.

Well, Crysis is more GPU driven than CPU, so low CPU usage should be normal. The only way to significantly increase performance in Crysis is to increase GPU horsepower.

so that would mean that i would need to play on low settings to play it properly so forgive my ignorance but i didnt pay over £150 for a gpu just to play on low settings i would of got a 6670 for that.

So that means something else is wrong because i know and have seen this card play on higher without a hitch.

did you install all the HD texture add-ons to crysis? if so that could be what's slowing you down

should still get 350W of useable power out of it :p  but yeah, wonder when it'll blow :pfff:

Ive had this psu for a year now and not a hitch i know its not the best but there are alot of good reviews out there but alot of people see one bad comment about them and automatically think its the same for every product well not me it works perfectly.
June 27, 2012 5:11:52 PM

And no there isnt any texture packs installed Thanks.
June 27, 2012 5:30:59 PM

if you haven't personally tried something then how can it be trash, anyways thats not the reason my gpu is running slow it has the power it needs.
June 27, 2012 5:34:16 PM

so in theory i have 468 watts.
June 27, 2012 5:36:13 PM

so what the cheapest psu i can get away with but still not a piece of crap lol.
June 27, 2012 5:37:58 PM

Yup.
June 27, 2012 5:38:08 PM

just FYI, the PSU is the single component in a computer that you don't want to take any chances with. most experienced builders are perfectly willing to give a little known company's mobo, GPU, memory, case etc a shot, but will say no way to a PSU until it's been tested extensively (either by themselves or by several hardware review sites such as TH's). the reason is that when your PSU goes, it can easily take the rest of your system with it, and that's typically saying "bye bye" to $1000+ of tech all because of a few dollars of savings on the PSU. a questionable PSU is like a time-bomb strapped to your system
June 27, 2012 5:40:36 PM

I understand that now which is why i need to know the least watts i would need for my setup?
June 27, 2012 5:47:53 PM

ok i will grab 1 of those will this help my gpu from the stutter i get on all my games? and would this let me overclock or will i need more power.

Run some 3DMark benchmarks and see if your card is performing as expected. You may be more sensitive to glitches in the game than other people are: when new textures are loaded or some background task kicks in, you may get glitches or hesitations even if your system is normally more than sufficient for the game.

Yes, a good PSU is a great thing, but I'd be surprised if changing the PSU is going to actually fix your issue.

Typically Seasonic, Corsair, Enermax, Antec, and a few others are the trusted brands. I'm not in the UK, but I'm sure Recon can give you great shopping advice

On 3dmark11 my score is 4053 i dont know if that is any good.

Your situation seems unnatural to me because of your Crysis situation. I am using a Geforce 9500 gt and I play Crysis on medium on a 24" monitor and mine is not jumpy.

Specs:

CPU: Intel Pentium D E2200
GPU: Nvidia GeForce 9500 GT
Power Supply: Rosewill Green Series 530W Continuous
MB: Whatever comes with a Dell Inspiron 530
Ram: 4gb 800mhz DDR2

Thats exactly why i don't understand it i see people with worse specs on youtube playing higher qaulity than me, it's really puzzling
