i currently have a his 6870 iceq with my i5 750 @stock with turbo on

i was thinking of upgrading to a his 6950 leaving my cpu @ stock with turbo mode enabled

oc cpu is not a option

will the his 6950 bottleneck with the i5 750 @ stock with turbo on

planning on upgrading my hdd to i.e a new 3.5 or a ssd

this is all in a effort to increase my fps in SWTOR as it is horrible in it atm

even GTX580 won't be bottleneck by that cpu at it's stock clock. why can't you OC the cpu? is it because of mobo? btw what kind of performance you're getting right now? based on the test done by toms even 6850 will have good performance on 1080p with maximum detail + 4MSAA (minimum frame rates = 40).

its a combination of hdd and video card i think because my aftermarket cooler is *** and i am not good with oc`ing cpu`s


if i put all settings to high in swtor u no it varies in some areas its 40 other places goes to 30 im just not happy with that

why did you suspect your hdd? have you tried suing different driver for your card? about OCing your cpu you can open new thread on overclocking section to ask for help.

another option i could slightly oc the 6870 in MSI afterburner like 975/1150 would save me some $

im using the latest driver 11.12 for it i had 11.11 and it was the same really

i just have a feeling the hdd is contributing to it to its a bit old

honestly i don't think old hdd will affect game performance directly. slow load? maybe. but slower fps? i don't think so

if i could get the 6870 stable at 975-1000 / 1150-1250 would that be enough?

not sure about that. but i expect even without OCing the card you should have good performance. have you tried clean driver install?

ye i did that not long ago i completley removed catalyst and all drivers i even went into device manager and uninstall the video card driver there to

i did that because something was conflicting and the text when i was in full screen with some games was a bit of

have you tried using driver sweeper program?

Yeah I agree with renz496, the HD6870 should be plenty of card to give quality performance. Does your motherboard support crossfire? I currently run two HD6870s in crossfire in my rig and they annihilate any game I throw at em'. another HD6870 would be cheaper than a HD6950 and I think they are about $179 right now

ye but id have to buy a new power supply and case for that cause of room would end up costing me more than a 6950

just a quick question when ocing should i leave fan on auto or set it to manual i put it to 975/1150 through msi afterburner and left fan on auto and the temp didnt go above 60 degrees didnt touch voltage either

Oh okay gotcha that makes sense. I'm assuming it never got above 60 degrees under load? or idle?

If that is load temps that is perfectly fine to leave the fan on auto, if that's a idle temp definitely run manual fan control and adjust accordingly. The HD6870 has a max temp of 105 degrees but you definitely want to stay well below that

under full load in msi kombustion test didnt go beyond 61-62 degrees at 975/1150 and 975/1200 with fan on auto

thats withouy touching any voltages its 1175 and havent touched it card comes at 900mhz/1050 default

i noticed a slight improvement in the score when doing it in afterburner comapred to to amd overdrive

Hard drives help with loading times, not frames. Also, 90% of the time if you want to crank up all the video options you also have to be willing to spend a lot more than the cost of a 6950 to be able to handle it at vsync. Depending on your res of course.

What res are you running?

I'll bet you can run a few settings on high and turn down the less important pretties and be al right with your card or even better a 6950.

so if u run all the stuff high or most of it at high if u have vsync turned on it makes it worse? i thought vsync just got rid of the lines across the screen

What resolution are you running? The 6870 should be able to deliver good performance in TOR at the highest settings up to 1080p, the game isn't a hugely demanding title when it comes to graphics. On most single displays the 6870 only really should struggle with the extremely demanding titles like Crysis, Crysis 2, or Metro 2033. In any case, getting a 6950 isn't going to help much, it's only 10% faster than the 6870, really not worth spending $250 for such a small upgrade. Your CPU should be fast enough for it, so I don't think that is a problem. How much RAM do you have? If the game is starved for memory, it has to pull data off the hard drive, and that will kill your framerates. If you have less than 4GB on your system, I would say get up to at least 4GB to facilitate good gaming performance.

You have stress tested it under furmark, so the card itself seems to be fine. It could be there is an issue with the game itself, you can try turning off vsync, sometimes it can cause performance issues. You may want to check the TOR forums and see if other people with similar hardware are running into performance issues, that would indicate either a driver problem, or a game problem, in which case there isn't much you can do except wait for a driver update/patch.

i just overclocked my gigabyte 6870 to 975/1150 and it did help in SWTOR but found the if i put shadows to low, with everything else on ultra it made the biggest improvement for fps. still dips down to 30 fps in really busy area's when it's first loading but was much better!
