[shahxaib]

idle temp is 64 , when in game 70 to 75. lol so true will get one. but for now I wanna see how much difference there will be.

want to see how much difference I will get. and 64 temp is when ac is off , else it will come down to 58.
tell me how can i overclock ?

 

[Cerberus]

u can overclock after changing supply...after changing supply do some over clock and check stability through OCCT and FUrmark...if its stable then do some more clocking

 

[shahxaib]

O yar right-click on you desktop > open the Catalyst Control Center > go to Performance/AMD Overdrive > unlock it > then do what ever you want.
You can check safe clock speeds, change fan speeds, check temps etc. Just buy a better PSU before tweaking it.

On a side note, it won't be much of a difference. I own a 4890 too. Regardless of whatever GPU you overclock the difference is mostly negligible in real world use.
