I bought a xfx radeon hd 6670 1gb ddr5 a couple of weeks ago, but for some reason any game i play even dirt 2 on low settings has lagging and screen tearing and only 20fps, these are my specs.

Thanks for replies, i have a 300w psu which im sure was enough when i read up on the 6670 power usage, as for temperature im getting around 50-60 ive tried uninstall and reinstall but still the same. ive tried 1280 720 but then i just get black borders which is not great.

Check your processes. There might be something robbing you of CPU power. Remember to enable all processes so you can actually see if there's a program draining some Juice.

300W PSU.. while it meets min video card spec, what brand is PSU? it could be the PSU is under-performing, you can see multiple Toms articles on how many PSU brands are substandard.

I'm guessing that at 300W it is likely a low grade chinese part which came with the case. A decent ~400 PSU can be found in the 20-30 dollar range, or you can test your current PSU to make sure it is outputting correct voltages.

Also, do you have many PCI components / drives? all components eat away at the available power, and a 300W PSU is 270-330W max. (10% tolerance is standard on power units, though some are rated for +/-20%)

If your positive it is not the PSU, what video driver are you installing?

No, any PSU in the $20-$30 range is not decent, I don't care what the wattage is. Unless it's on sale, it's almost impossible to find decent PSUs for less than $50 at any wattage.

For example, the cheapest units from various reputable brands on Newegg:

Corsair 430W: $49.99
SeaSonic 300W: $43.99
Antec 350W: $39.99
PC Power and Cooling 400W: $69.99

Good PSUs cost a lot more than $30.
 
the reason why usually built in psu in cases are bad is because they aren't certified. A company can sell you a 700w psu, but it not being certified means no one can guarantee that that psu will hold out at 700w, heck maybe not even at 400w. Certifications are there to prove that a psu can at least have 80% efficiency during load. if your psu cannot supply enough power to the computer at a steady rate, performance is drained. I have seen it myself first hand when my friend stuck a 8400 gs in his old sony desktop.

A would be a good idea to swap psu. 40-50$ can shell out a good low end bronze certified psu (Antec Earthwat 380w)

so in theory then it is definately to do with the psu nothing else? So what would be the watts i would need to have this gpu running perfectly, and maybe be able to run other graphics cards like radeon hd 6850 because this will be my next card within the next year.

Agreed, Good (80% efficiency) PSUs do cost 50, i said decent, and i was thinking of a 70% efficiency name brand I have had good experience with, but admittedly, I was thinking of sale prices I saw 2 weeks ago.

Back on topic, here are good guides to help you decide on a new PSU.

As to other causes for your errors, PSU is first point, but could be graphics driver or as eluded to, processor bottleneck. Seeing your system specs, and age of card vs # of drivers released since launch, i would lean towards PSU.

I also stated earlier that i am never reaching over 50% whilst playing games and not over 1% while doing nothing, i played the witcher 2 on lowest still lag so i thought could be the game so i tried dirt 2 on low and nfs the run still all screen tearing and jumpy on even the lowest settings, ive uninstalled all drivers and reinstalled again with no prevail so its kinda bugging me.

Could it be screen resolution or my vga cable, i have tried different resolutions but every resolution apart from standard 1920x1080 60hz has huge borders round it so i cant get it full screen.

Thats the point of the boarders however. To bring the res down. Try it at a lower res as your 6670 is not good for 1080 gaming.

You might also want to try one of those driver sweeper/cleaning programs.

first of all have you plugged the wire in correct port and i think u must upgrade your power supplier as the AMD cards eats a lot of power so i recommend you to buy 450 above power supplier

your computer is far good enough to play battlefield 3 at high settings..

i think this might help..... :)

Lower resolutions doesnt help whatsoever, as for the wire it doesnt have one, power consumption is 280 max i have 300watts so it should be fine. but i will buy a new psu anyways 500watt corsair from amazon.
