Ati 6850 vs xfx 9800 gtx+

make and model of psu?

At that resolution, I would not recommend the 6850. Not unless you plan on upgrading the monitor soon. What are your complete specs?

If your rig is unstable with a 600w power supply it's not going to become more stable if you replace the video card. Either your power supply is a piece of crap and should be replaced, or your too agressive with your overclock, 600w is more than plenty for an i7 and a 9800 or a 6850.

totally agreed

My specs are : intel i7 920, intel dx58so mobo, 3 gb 1333 ghz kingston ram, 1 tb samsung hdd, 320 gb seagate hdd, zebronics realwatts pro 600 psu, lg dvd writer, xfx 9800 gtx+ video card, Acer AL1706 17" lcd.


My rig is stable in this state but if i enable turbo mode for cpu, in some games at intense moments, my pc hangs and reboots. I have sorted out that this is due to lack of psu power. Now i read that 6850 requires less power in peak mode than 9800 gtx+. So if i use it, won't i get some extra power for the cpu overclock ? say to up to 3.6 ghz ?

Why not just replace the power supply? Yours is already failing, seems not too smart to go out and spend 160-180 bucks on a video card when your $25 PSU might blow up and ruin it all.

yeah you should be doing no ocing with that crap psu you have, get a quality psu, heck even an antec earthwatts 380w would do the trick, get a reliable psu before upgrading your gpu like many have already said

great reviews and good warranty. I have personally installed this PSU in a number of computers for myself and for customers and I haven't had any of them returned or DOA.

But i was thinking that i could get a lot better fps in my games with just replacing the video card and save some power too at the same time with the 6850. Getting a new psu is the clean option .. but i was looking for that shortcut to better performance with 6850. Any takers ?

You could get 0 fps if your PSU blows up. Safety first  

The 9800GTX+ is a powerful card but at those resoultions I don't think you'd see a huge improvement if you upgraded to the 6850,at those low reosultions games relay more on raw CPU power than GPU abilites.

No name brand PSU's like the one you have are not reliable to say the least.Even tho it is a 600watt PSU it's probably only really capable of delievering 200watts if your saying it's power releated.If thats the case your 9800GTX+ is prolly downclocking to save it self from frying which in turn will reduce it's performance.

Another reason why your computer crash's is that you may have a bad chip or something is wrong with the voltage regulation between the PSU and the motherboard and CPU.Some componet is not giving or not the correct amount of voltage to the processor.It is crashing because it's unstable at the higher speeds because it's not getting as much voltage as it should.
