I am currently using the xfx 9800 gtx+ with my i7 rig and the psu is 600 watts.. well my system just about does the job @ 1280 x 1024 res while playing heavy duty games at high settings. But now i am reading that the new ati (any variation) 6850 requires less power than even the 9800 gtx+ (this is an overclocked 65nm version of 9800 gtx and not the 55nm one).

My question is if i replace my gtx+ with this 6850, will i have more psu power for overclocking my cpu and run my rig more stably ? Currently i am running my i7 cpu @ stock speeds with turbo mode and hyperthreading disabled.

More about : ati 6850 xfx 9800 gtx

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.

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

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.
