Should i get this new gpu?

So i've been thinking of upgrading my gpu (ive got a Radeon 7850 hd with 2gb of gddr5) and ive came across this link - http://www.umart.com.au/umart1/pro/Products-details.phtml?id=10&bid=6&id2=185&sid=186132 - its much cheaper than most of the things that i could find in australia -.-

 

I edit a lot and some gaming, is this a good idea to get this new gpu?

 

My build -

MotherBoard: ASrock B75M R2

CPU: Intel Core i3 3240 

GPU: AMD radeon HD 7850 2GB GDDR5

RAM: 8GB of DDR3 1600mhz Ram (corsair vengeance)

HDD: Western Digital Blue 1TB

PSU: Corsair VS650

Case: Cooler Master elite 431 plus

you would be getting better performance if you instead bought a second 7000 series card to suppliment the performance of your current 7850, but if you cannot afford the wattage hit go with the R9 280.

Mobo is xfire compatible , and your psu is good enough ( I think )

So get a second 7850 , they are now called r9 270 .

If you can , get the 7850 to avoid problems , but if it's cheaper get the r9 270

If you join up on OCAU forums - after 60 days you can buy/trade parts. There is a shit load of 7970's, 280's, 290's for dirt cheap at the moment. Just yesterday there was a 7970 for 150. Its a good community so very little chance of shit being dodgy.

Peace.
