hi all, i am planning to upgrade my pc..currently i use xfx hd4770, n wanna to get another one for crossfire..i tried to see some reviews n it sounds impressive, but most of the reviews use high-end mobo where they all run both GPU at x16 lane.mean x16 at first lane and x16 at 2nd lane. but mine is Gigabyte Ma790gp-ud4h..where first lane would be x16 but 2nd would be x8 only..would it affect the real&significant performance compared to both running at x16? or does anybody have tried to test this two GPU on the same mobo or likely? hope can get some guidance from anyone n sifu here.. thanx.

oic..so far I don't have budget to go for 4890 although I sell my current, I need to add 3** more. by the way, I am thinking back that my PSU is CM Real Power Pro 550W, so if I want to make a CF, maybe I need more wattage PSU...is it correct?

QUOTE(InFe_eD @ Nov 6 2009, 05:42 PM) Nope, it's perfectly fine. My fren run his rig with 8800gt and another 8600 as physX card using only huntkey 500w, no problem at all. There are too many "PRO" here spread around stupid information that every1 shud get a 800w or 1000w psu  oic..but if I change to 4890 then it mayb I need to change PSU rite? |
