Hi all,

I want to OC my graphic card for better performance in playing games. First of all, the specs of my rig;

Intel i5-3470 3.2
Asus p8h77-m
Sapphire hd 7850 2gb OC
Westrn digitl 1tb
8 gb ram
Fsp hexa 500w
casing CM K280 (added 1 side and 1 rear fan)

Based on the above specs, i need to know if i need to add any additional cooling system or if i need to change my casing for a better air circulation when i OC the GPU... If need an additional cooler or need to change the case, any suggestion? I have RM300 budget for any add-ons or changes...

Thanks all..

In addition to the above, if i need to upgrade my PSU?

Thanks..

need not change anything.

just download a GPU overclocking software.

use Sapphire's TRIXX. Simple interface, maximize your core while minimize your voltage (if option available).

don't expect great performance boost though. 50 - 100mhz boost usually gives you around 3 - 5 frames extra.

any particular game you wanna play bro?. where your rig at? is it in your bedroom?or living room?. ur screen resolution also need to take into consideration.
if ur rig located at cold enviroment, u sure can OC harder by increasing ur GC clock. some guide regarding OC can be found here
