Radeon 7950 not running at full potential

About a week ago i upgraded my computer, and i have seen no improvement at all in anything, in fact it seems worse. I like to make 3d art and animation thats why i got the 7950, and at first the drivers were all messed up because AMD created many bugs as it seems, so i got a modded version of the drivers and CCC, that fixed some Open GL issues but thats about all. all my new parts were put in then a clean install of windows 7 was done,my PC recognizes the new parts but doesn't seem to utilize them, it takes even longer to render the same thing in Cinema 4D with the 7950 than it did with a 6850. and also games have low framerates (probably due to my projector) but the PC seems way too slow with the parts i put in it.

Specs of before upgrade :
CPU - AMD Phenom x6 black edition
GPU - Gigabyte Radeon 6850 1gb
Mobo - Gigabyte 990FXA-UD3 (rev 1.0)
RAM - Gskill ripjaws 2x 4gb
Case - Thermaltake Overseer
HDD - WD 500gb
Cool - Thermaltake closed loop liquid cooling
PSU - Coolermaster 550 watt

Specs after 'upgrade' :
CPU - AMD FX 8350 Black edition
GPU - Gigabyte Radeon 7950 3Gb
Mobo - Gigabyte 990FXA-UD3 (rev 1.0)
RAM - Gskill ripjaws 4x 4gb
Case - Thermaltake Overseer
HDD - WD 500gb
Cool - stock AMD heatsink
PSU - master 650 watt

Welcome, Jozer12, on the ROG Forum!

What is the exact model of your PSU? More precisely, is it handling the power requirements of the HD7950?

Also, if you want to have a real jump in speed, I would advise you to start using an SSD drive....

the PSU, its called a 'Master 650 wt" no model number that i can trace to anywhere. I'm pretty sure it can handle it, its power requirements are 500 watts, and SSD or HDD, i dont think not having a SSD should make my computer function worse when i gave it new and good hardware

Oh you won't know your PC when you slap an SSD into it, it'll run like a demon :cool:

still, the point is ive had a performance decrease since i put new parts in 😕 Any recomendations on a cheap but good SSD?

Yes, you will be amazed how fast it will be with an SSD! I think, for everyday use, switching to an SSD from HDD is the biggest speed jump... - at least what you can feel and not only the benchmarks... - I would recommend a 128GB Samsung 830 or 840, now they're pretty cheap/less expensive and they're very good...

Now, I could not find your PSU... it really does matter which exact model do you have... your graphics card may need more power than the PSU can supply on the rail... and I'm thinking here about the amperage... - so, if you can not find the exact model on it, try to search the internet... a link with the product page from where you got it would help... (also, would be nice for the graphics card too)

Is this the SSD you were talking about? http://www.centrecom.com.au/catalog/7td120bw-samsung-120gb-p-61686.html?sort=3a
How do you put your whole operating system on it? do you think i need a new mobo? i think my mobo doesn't want to properly recognise my CPU, i needed to do a BIOS update for it and i think its slow because the mobo doesn't properly support it

Heres the link to my GFX card http://www.centrecom.com.au/catalog/r795wf3-gigabyte-radeon-7950-overclocked-p-56327.html?sort=3a. I dont know how but i could not find the PSU, i bought it from the same people

The 8350 is a pretty new CPU so the Gigabyte 990FXA-UD3 might not support it straight out of the box without doing a BIOS update. It's completely normal. Once the update is done, there should be no problem.

Your new system should show a considerable improvement over your old system. SSD functions just the same as HDD. Just faster. You'll need to reinstall Windows and all your programs on it. But since it's a lot faster than a regular HDD, you won't even notice the time.

Your PSU sounds very generic. I don't know what the specs are but I wouldn't run a high end system with something like that. I always recommend a CoolerMaster PSU as a minimum if the client is on a tight budget.
