games running worse with new gpu??

[ezroller]

hi all, another noob post but cant really find anything similar online,

well i got an asus amd radeon 6670 2gb GPU to use instead of my APUs built in one, and although i get a better windows experience and performancetest score games now seem to run really badly? on steam games like counterstrike GO and portal 2 i used to run them at medium settings and they ran smoothly but now everything jitters a little and lags a lot when theres a lot going on in the game, even on lowest settings?

ive made sure the drivers are updated and made sure its only running from the new GPU but no luck there, tried the IGPU again and it ran smoothly again?

am i missing something here? i assumed it would run better but this is much worse,

if it helps im running an....

ASUS amd A6-3620 4 core 2.2ghz clocked to 2.8
8gb ddr3 1600mhz ram

the IGPU was a HD 6530d which is now disabled and running from the above ASUS amd redeon 6670 2gb

if anyone can help thatd be great as itd be annoying to go back to the IGPU just because i was doing something wrong

Drivers installed? What PSU?

Got it in the right PCI-E slot?

Ensure the 6530D is really disabled and is not running together with the 6670 in Dual graphics mode? If it really is running in Dual graphics mode, you need to install AMD CAPS since it's a type of crossfire: http://sites.amd.com/us/game/downloads/pages/crossfirex-app-profiles.aspx

yeah got the latest drivers from the website, also steam did a check and that said i had the newest ones.

it says its only running from the 6670, no mention in any of the options of it running from both. had a look in bios and its selected the PCI as main card, there was a setting for the IGPU but the only options were auto or enabled..

im pretty sure its in the right PCI slot, there are 4, only 2 of which would fit the card and then 1 of them is right at the bottom of the case so wouldnt fit well in there anyway. before this card i had put an asus geforce gt620 1gb card in there which ran better than the internal one did, although i didnt run any tests so cant say how much better but everything was quicker and let me turn up the settings a notch.

the PSU is a pretty cheap looking 350w affair, cant remember the model as im at work but did do a quick search last night, didnt find any real info but there was a thread from here that came up about a guy with the same PSU having problems with his nvidia GPU staying at 90 degrees C all the time even when idling, dont know if that helps.
