[ins]

machooo...i juz got a 4890 and a 4850 asus vgacard frm Malaysia.brand new...so hw can i check it whether its working perfectly o not???

im using an asus 4870 currently..if tha 4890 is gud im plannin ta upgrade it.....and iv already talkd ta a buyer fa tha 4850 and ma old 4870...

i hav a 550w psu...buh if im goin to plug tha 4890 il be needing ta buy a 650w psu(coz of tha 8pin)..

buh im abit curious wether tha 4890 is working perfectly or not????coz its pointless spending 15k fa a psu if tha vga is aint good...
i hope u can undstand...
